Predictors of participation of adolescents with cerebral palsy: A European multi-centre longitudinal study.

We investigated whether childhood factors that are amenable to intervention (parenting stress, child psychological problems and pain) predicted participation in daily activities and social roles of adolescents with cerebral palsy (CP). We randomly selected 1174 children aged 8-12 years from eight population-based registers of children with CP in six European countries; 743 (63%) agreed to participate. One further region recruited 75 children from multiple sources. These 818 children were visited at home at age 8-12 years, 594 (73%) agreed to follow-up at age 13-17 years. We used the following measures: parent reported stress (Parenting Stress Index Short Form), their child's psychological difficulties (Strength and Difficulties Questionnaire) and frequency and severity of pain; either child or parent reported the child's participation (LIFE Habits questionnaire). We fitted a structural equation model to each of the participation domains, regressing participation in childhood and adolescence on parenting stress, child psychological problems and pain, and regressing adolescent factors on the corresponding childhood factors; models were adjusted for impairment, region, age and gender. Pain in childhood predicted restricted adolescent participation in all domains except Mealtimes and Communication (standardized total indirect effects ß -0.05 to -0.18, 0.01

Self-reported quality of life of adolescents with cerebral palsy: a cross-sectional and longitudinal analysis.

BACKGROUND: Children with cerebral palsy who can self-report have similar quality of life (QoL) to their able-bodied peers. Is this similarity also found in adolescence? We examined how self-reported QoL of adolescents with cerebral palsy varies with impairment and compares with the general population, and how factors in childhood predict adolescent QoL. METHODS: We report QoL outcomes in a longitudinal follow-up and cross-sectional analysis of individuals included in the SPARCLE1 (childhood) and SPARCLE2 (adolescent) studies. In 2004 (SPARCLE1), a cohort of 818 children aged 8-12 years were randomly selected from population-based cerebral palsy registers in nine European regions. We gathered data from 500 participants about QoL with KIDSCREEN (ten domains); frequency of pain; child psychological problems (Strengths and Difficulties Questionnaire); and parenting stress (Parenting Stress Index). At follow-up in 2009 (SPARCLE2), 355 (71%) adolescents aged 13-17 years remained in the study and self-reported QoL (longitudinal sample). 76 additional adolescents self-reported QoL in 2009, providing data for 431 adolescents in the cross-sectional sample. Researchers gathered data at home visits. We compared QoL against matched controls in the general population. We used multivariable regression to relate QoL of adolescents with cerebral palsy to impairments (cross-sectional analysis) and to childhood QoL, pain, psychological problems, and parenting stress (longitudinal analysis). FINDINGS: Severity of impairment was significantly associated (p<0·01) with reduced adolescent QoL on only three domains (Moods and emotions, Autonomy, and Social support and peers); average differences in QoL between the least and most able groups were generally less than 0·5 SD. Adolescents with cerebral palsy had significantly lower QoL than did those in the general population in only one domain (Social support and peers; mean difference -2·7 [0·25 SD], 95% CI -4·3 to -1·4). Pain in childhood or adolescence was strongly associated with low adolescent QoL on eight domains. Childhood QoL was a consistent predictor of adolescent QoL. Child psychological problems and parenting stress in childhood or their worsening between childhood and adolescence predicted only small reductions in adolescent QoL. INTERPRETATION: Individual and societal attitudes should be affected by the similarity of the QoL of adolescents with and without cerebral palsy. Adolescents with cerebral palsy need particular help to maintain and develop peer relationships. Interventions in childhood to alleviate psychological difficulties, parenting stress, and especially pain, are justified for their intrinsic value and for their longer term effect on adolescent QoL. FUNDING: SPARCLE1 was funded by the European Union Research Framework 5 Program (grant number QLG5-CT-2002-00636), the German Ministry of Health GRR-58640-2/14, and the German Foundation for the Disabled Child.

Surgical interventions for high-grade vulval intraepithelial neoplasia.

BACKGROUND: This is an updated version of an original Cochrane review published in The Cochrane Library, 2011, Issue 1.Vulval intraepithelial neoplasia (VIN) is a pre-malignant condition of the vulval skin. This uncommon chronic skin condition of the vulva is associated with a high risk of recurrence and the potential to progress to vulval cancer. The condition is complicated by its multicentric and multifocal nature. The incidence of this condition appears to be rising, particularly in the younger age group. There is a lack of consensus on the optimal surgical treatment method. However, the rationale for the surgical treatment of VIN has been to treat the symptoms and exclude any underlying malignancy, with the continued aim of preserving the vulval anatomy and function. Repeated treatments affect local cosmesis and cause psychosexual morbidity, thus impacting he individual's quality of life. OBJECTIVES: To evaluate the effectiveness and safety of surgical interventions in women with high-grade VIN. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Group Trials Register and the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 11,2013 and MEDLINE and EMBASE up to December 2013. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies, and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) that compared surgical interventions in adult women diagnosed with high-grade VIN. DATA COLLECTION AND ANALYSIS: Two review authors independently abstracted data and assessed risk of bias. MAIN RESULTS: We identified one RCT, including 30 women, that met our inclusion criteria; this trial reported data on carbon dioxide (CO2) laser surgery versus cavitational ultrasonic surgical aspiration (CUSA). There were no statistically significant differences in the risks of disease recurrence after one year of follow-up, pain, scarring, dysuria or burning, adhesions, infection, abnormal discharge or eschar between women who underwent CO2 laser surgery and those who received CUSA. The trial lacked statistical power due to the small number of women in each group and the low number of observed events, but was at low risk of bias. AUTHORS' CONCLUSIONS: The included trial lacked statistical power due to the small number of women in each group and the low number of observed events. The absence of reliable evidence regarding the effectiveness and safety of the two surgical techniques for the management of VIN therefore precludes any definitive guidance or recommendations for clinical practice.

European study of frequency of participation of adolescents with and without cerebral palsy.

Children with cerebral palsy participate less in everyday activities than children in the general populations. During adolescence, rapid physical and psychological changes occur which may be more difficult for adolescents with impairments. Within the European SPARCLE project we measured frequency of participation of adolescents with cerebral palsy by administering the Questionnaire of Young People's Participation to 667 adolescents with cerebral palsy or their parents from nine European regions and to 4666 adolescents from the corresponding general populations. Domains and single items were analysed using respectively linear and logistic regression. Adolescents with cerebral palsy spent less time with friends and had less autonomy in their daily life than adolescents in the general populations. Adolescents with cerebral palsy participated much less in sport but played electronic games at least as often as adolescents in the general populations. Severity of motor and intellectual impairment had a significant impact on frequency of participation, the more severely impaired being more disadvantaged. Adolescents with an only slight impairment participated in some domains as often as adolescents in the general populations. Regional variation existed. For example adolescents with cerebral palsy in central Italy were most disadvantaged according to decisional autonomy, while adolescents with cerebral palsy in east Denmark and northern England played sports as often as their general populations. Participation is an important health outcome. Personal and environmental predictors of participation of adolescents with cerebral palsy need to be identified in order to design interventions directed to such predictors; and in order to inform the content of services.

Surgery for cervical intraepithelial neoplasia.

BACKGROUND: Cervical intraepithelial neoplasia (CIN) is the most common pre-malignant lesion. Atypical squamous changes occur in the transformation zone of the cervix with mild, moderate or severe changes described by their depth (CIN 1, 2 or 3). Cervical intraepithelial neoplasia is treated by local ablation or lower morbidity excision techniques. Choice of treatment depends on the grade and extent of the disease. OBJECTIVES: To assess the effectiveness and safety of alternative surgical treatments for CIN. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (up to November 2012). We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) of alternative surgical treatments in women with cervical intraepithelial neoplasia. DATA COLLECTION AND ANALYSIS: Two review authors independently abstracted data and assessed risks of bias. Risk ratios that compared residual disease after the follow-up examination and adverse events in women who received one of either laser ablation, laser conisation, large loop excision of the transformation zone (LLETZ), knife conisation or cryotherapy were pooled in random-effects model meta-analyses. MAIN RESULTS: Twenty-nine trials were included. Seven surgical techniques were tested in various comparisons. No significant differences in treatment failures were demonstrated in terms of persistent disease after treatment. Large loop excision of the transformation zone appeared to provide the most reliable specimens for histology with the least morbidity. Morbidity was lower than with laser conisation, although the trials did not provide data for every outcome measure. There were not enough data to assess the effect on morbidity when compared with laser ablation. AUTHORS' CONCLUSIONS: The evidence suggests that there is no obvious superior surgical technique for treating cervical intraepithelial neoplasia in terms of treatment failures or operative morbidity.

Pain in young people aged 13 to 17 years with cerebral palsy: cross-sectional, multicentre European study.

OBJECTIVE: To determine the prevalence and associations of self- and parent-reported pain in young people with cerebral palsy (CP). DESIGN AND SETTING: Cross-sectional questionnaire survey conducted at home visits in nine regions in seven European countries. Participants were 13 to 17-year-olds (n=667) drawn from population CP registers in eight regions and from multiple sources in one region. 429 could self-report; parent-reports were obtained for 657. Data were collected on: severity, frequency, site and circumstances of pain in previous week; severity of pain associated with therapy in previous year. RESULTS: The estimated population prevalence of any pain in previous week was 74% (95% CI 69% to 79%) for self-reported pain and 77% (95% CI 73% to 81%) for parent-reported pain. 40% experienced leg pains, 34% reported headaches and 45% of those who received physiotherapy experienced pain during therapy. Girls reported more pain than boys (OR=2.1, 95% CI 1.5 to 3.0) and young people reported more pain if they had emotional difficulties (comparing highest and lowest quartiles: OR=3.1, 95% CI 1.7 to 5.6). Parents reported more pain in children with emotional difficulties (OR=4.2, 95% CI 2.7 to 6.6), or with more impaired walking ability. CONCLUSIONS: Pain in young people with CP is highly prevalent. Because pain causes immediate distress and is associated with lower subjective well-being and reduced participation, clinicians should routinely assess pain. Clinical interventions to reduce pain should be implemented and evaluated. The efficacy of medical and therapeutic interventions causing pain should be re-examined to establish if their benefit justifies the pain and fear of pain that accompany them.

A systematic review of fish-oil supplements for the prevention and treatment of hypertension.

AIMS: Fish oils are widely believed to promote cardiovascular health by lowering blood pressure (BP) but the evidence supporting this is not conclusive. We aimed to systematically review existing evidence. METHOD: We undertook a systematic review of randomized controlled trials and crossover trials that evaluated the effectiveness of fish-oil supplements. We included trials enrolling adults who were given fish-oil supplements with at least 8 weeks' follow up. Effects on systolic and diastolic BP were assessed using meta-analysis. Meta-regression was undertaken to explore the relationship between dose of fish oil and BP outcomes. RESULTS: We included 17 studies, with a total of 1524 participants. We explored the effects of fish-oil supplements in both normotensive and hypertensive participants with BP 140/85 mmHg at least. Meta-analyses were performed using the inverse-variance method. Data from eight studies in hypertensive participants found a statistically significant reduction in systolic and diastolic BP; 2.56 mmHg (95% CI 0.58 to 4.53) and 1.47 mmHg (95% CI 0.41 to 2.53), respectively. Nine studies in normotensive participants showed a non-significant reduction in both systolic and diastolic BP. Meta-regression showed no significant relationship between dose of fish oil and the effect on BP. CONCLUSION: The small but statistically significant effects of fish-oil supplements in hypertensive participants in this review have important implications for population health and lowering the risk of stroke and ischaemic heart disease. Their modest effects, however, mean that they should not be recommended as an alternative to BP-lowering drugs where guidelines recommend treatment.

Association between participation in life situations of children with cerebral palsy and their physical, social, and attitudinal environment: a cross-sectional multicenter European study.

OBJECTIVE: To evaluate how participation of children with cerebral palsy (CP) varied with their environment. DESIGN: Home visits to children. Administration of Assessment of Life Habits and European Child Environment Questionnaires. Structural equation modeling of putative associations between specific domains of participation and environment, while allowing for severity of child's impairments and pain. SETTING: European regions with population-based registries of children with CP. PARTICIPANTS: Children (n=1174) aged 8 to 12 years were randomly selected from 8 population-based registries of children with CP in 6 European countries. Of these, 743 (63%) agreed to participate; 1 further region recruited 75 children from multiple sources. Thus, there were 818 children in the study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Participation in life situations. RESULTS: For the hypothesized associations, the models confirmed that higher participation was associated with better availability of environmental items. Higher participation in daily activities-mealtimes, health hygiene, personal care, and home life-was significantly associated with a better physical environment at home (P<.01). Mobility was associated with transport and physical environment in the community. Participation in social roles (responsibilities, relationships, recreation) was associated with attitudes of classmates and social support at home. School participation was associated with attitudes of teachers and therapists. Environment explained between 14% and 52% of the variation in participation. CONCLUSIONS: The findings confirmed the social model of disability. The physical, social, and attitudinal environment of disabled children influences their participation in everyday activities and social roles.

Predictors of drop-out in a multi-centre longitudinal study of participation and quality of life of children with cerebral palsy.

BACKGROUND: SPARCLE is a study across nine European regions which examines the predictors of participation and quality of life of children with cerebral palsy. Children and their families were initially interviewed in 2004/2005 when the children were aged 8-12 years (SPARCLE1); they were approached again in 2009/2010 at age 13-17 years (SPARCLE2). The objective of this report is to assess potential for bias due to family non-response in SPARCLE2. Logistic regression was used to assess whether socio-demographic factors, parental stress and child impairment were related to non-response, both overall and by category (failure to trace families, death of child, traced families declining to participate). RESULTS: Of the 818 families who participated in SPARCLE1, 224/818 (27%) did not participate in SPARCLE2. 51/818 (6%) were not traced. Among the 767 traced families, 32/767 (4%) children with cerebral palsy had died, seven children had been incorrectly diagnosed as having cerebral palsy, thirteen families had moved out of the region and one family had language problems. Of the remaining 714 families, 120/714 (17%) declined to participate. Drop-out between SPARCLE1 and SPARCLE2 varied significantly between regions; families were more difficult to trace and more likely to decline to participate if the parents' educational qualifications, as recorded in SPARCLE1, were lower; they were also more likely to decline to participate if SPARCLE1 recorded that they were more stressed or if they had not completed a SPARCLE1 stress questionnaire. CONCLUSIONS: To reduce the risk of bias, all SPARCLE2 analyses should allow for factors (region and walking ability) which determined the sampling strategy, either by adjusting for these factors or by using sampling weights. Further analyses should be performed, adjusting for additional factors that were associated with non-response: parents' educational qualifications, family structure and parental stress. To allow for differential non-response in studies which sample from population registers, such registers should routinely record socio-demographic information.

Radiotherapy and chemoradiation after surgery for early cervical cancer.

BACKGROUND: This is an updated version of the original Cochrane review first published in Issue 4, 2009. There is an ongoing debate about the indications for, and value of, adjuvant pelvic radiotherapy after radical surgery in women with early cervical cancer. Certain combinations of pathological risk factors are thought to represent sufficient risk for recurrence, that they justify the use of postoperative pelvic radiotherapy, though this has never been shown to improve overall survival, and use of more than one type of treatment (surgery and radiotherapy) increases the risks of side effects and complications. OBJECTIVES: To evaluate the effectiveness and safety of adjuvant therapies (radiotherapy, chemotherapy followed by radiotherapy, chemoradiation) after radical hysterectomy for early-stage cervical cancer (FIGO stages IB1, IB2 or IIA). SEARCH METHODS: For the original review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 4, 2008. The Cochrane Gynaecological Cancer Group Trials Register, MEDLINE (January 1950 to November 2008), EMBASE (1950 to November 2008). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. For this update, we extended the database searches to September 2011 and searched the MetaRegister for ongoing trials. SELECTION CRITERIA: Randomised controlled trials (RCTs) that compared adjuvant therapies (radiotherapy, chemotherapy followed by radiotherapy, or chemoradiation) with no radiotherapy or chemoradiation, in women with a confirmed histological diagnosis of early cervical cancer who had undergone radical hysterectomy and dissection of the pelvic lymph nodes. DATA COLLECTION AND ANALYSIS: Two review authors independently abstracted data and assessed risk of bias. Information on grade 3 and 4 adverse events was collected from the trials. Results were pooled using random-effects meta-analyses. MAIN RESULTS: Two RCTs, which compared adjuvant radiotherapy with no adjuvant radiotherapy, met the inclusion criteria; they randomised and assessed 397 women with stage IB cervical cancer. Meta-analysis of these two RCTs indicated no significant difference in survival at 5 years between women who received radiation and those who received no further treatment (risk ratio (RR) = 0.8; 95% confidence interval (CI) 0.3 to 2.4). However, women who received radiation had a significantly lower risk of disease progression at 5 years (RR 0.6; 95% CI 0.4 to 0.9).Although the risk of serious adverse events was consistently higher if women received radiotherapy rather than no further treatment, these increased risks were not statistically significant, probably because the rate of adverse events was low. AUTHORS' CONCLUSIONS: We found evidence, of moderate quality, that radiation decreases the risk of disease progression compared with no further treatment, but little evidence that it might improve overall survival, in stage IB cervical cancer. The evidence on serious adverse events was equivocal.

Centralisation of services for gynaecological cancers - a Cochrane systematic review.

OBJECTIVE: Gynaecological cancers are the second most common cancers among women. It has been suggested that centralised care improves outcomes but consensus is lacking. This systematic review assesses the effectiveness of centralisation of care for patients with gynaecological cancer, in particular, survival advantage. METHODS: A comprehensive search of the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL (The Cochrane Library, Issue 4, 2010), MEDLINE, and EMBASE up to November 2010 was conducted. Registers of clinical trials, abstracts of scientific meetings, and reference lists of included studies were also searched. Randomised controlled trials (RCTs), quasi-RCTs, controlled before-and-after studies, interrupted time series studies, and observational studies were included and multivariable analysis to adjust for baseline case mix were used. RESULTS: Five retrospective observational studies met the inclusion criteria. Meta-analysis of three studies assessing over 9000 women suggested that institutions with gynaecologic oncologists on site may prolong survival in women with ovarian cancer, compared to community or general hospitals: hazard ratio (HR) of death was 0.90 (95% confidence interval (CI) 0.82 to 0.99). Similarly, another meta-analysis of three studies assessing over 50,000 women, found that teaching centres or regional cancer centres may prolong survival in women with any gynaecological cancer compared to community or general hospitals (HR 0.91; 95% CI 0.84 to 0.99). The largest of these studies included all gynaecological malignancies and assessed 48,981 women, so the findings extend beyond ovarian cancer. One study compared community hospitals with semi-specialised gynaecologists versus general hospitals and reported non-significantly better disease-specific survival in women with ovarian cancer (HR 0.89; 95% CI 0.78 to 1.01). The findings of included studies were highly consistent. CONCLUSIONS: The meta-analysis provides evidence to suggest that women with gynaecological cancer who received treatment in specialised centres had longer survival than those managed elsewhere.

Centralisation of services for gynaecological cancer.

BACKGROUND: Gynaecological cancers are the second most common cancers among women. It has been suggested that centralised care improves outcomes but consensus is lacking. OBJECTIVES: To assess the effectiveness of centralisation of care for patients with gynaecological cancer. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL (The Cochrane Library, Issue 4, 2010), MEDLINE, and EMBASE up to November 2010. We also searched registers of clinical trials, abstracts of scientific meetings, and reference lists of included studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs, controlled before-and-after studies, interrupted time series studies, and observational studies that examined centralisation of services for gynaecological cancer, and used multivariable analysis to adjust for baseline case mix. DATA COLLECTION AND ANALYSIS: Three review authors independently extracted data, and two assessed risk of bias. Where possible, we synthesised the data on survival in a meta-analysis. MAIN RESULTS: Five studies met our inclusion criteria; all were retrospective observational studies and therefore at high risk of bias.Meta-analysis of three studies assessing over 9000 women suggested that institutions with gynaecologic oncologists on site may prolong survival in women with ovarian cancer, compared to community or general hospitals: hazard ratio (HR) of death was 0.90 (95% confidence interval (CI) 0.82 to 0.99). Similarly, another meta-analysis of three studies assessing over 50,000 women, found that teaching centres or regional cancer centres may prolong survival in women with any gynaecological cancer compared to community or general hospitals (HR 0.91; 95% CI 0.84 to 0.99). The largest of these studies included all gynaecological malignancies and assessed 48,981 women, so the findings extend beyond ovarian cancer. One study compared community hospitals with semi-specialised gynaecologists versus general hospitals and reported non-significantly better disease-specific survival in women with ovarian cancer (HR 0.89; 95% CI 0.78 to 1.01). The findings of included studies were highly consistent. Adverse event data were not reported in any of the studies. AUTHORS' CONCLUSIONS: We found low quality, but consistent evidence to suggest that women with gynaecological cancer who received treatment in specialised centres had longer survival than those managed elsewhere. The evidence was stronger for ovarian cancer than for other gynaecological cancers.Further studies of survival are needed, with more robust designs than retrospective observational studies. Research should also assess the quality of life associated with centralisation of gynaecological cancer care. Most of the available evidence addresses ovarian cancer in developed countries; future studies should be extended to other gynaecological cancers within different healthcare systems.

Cardioprotective interventions for cancer patients receiving anthracyclines.

BACKGROUND: Anthracyclines are among the most effective chemotherapeutic agents in the treatment of numerous malignancies. Unfortunately, their use is limited by a dose-dependent cardiotoxicity. In an effort to prevent this cardiotoxicity, different cardioprotective agents have been studied. OBJECTIVES: The objective of this review was to assess the efficacy of different cardioprotective agents in preventing heart damage in cancer patients treated with anthracyclines. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 10), MEDLINE (1966 to November 2010) and EMBASE (1980 to November 2010) databases. In addition, we handsearched reference lists, conference proceedings of the International Society of Paediatric Oncology (SIOP) and American Society of Clinical Oncology (ASCO) meetings (1998 to 2010) and ongoing trials registers. SELECTION CRITERIA: Randomised controlled trials (RCTs) in which any cardioprotective agent was compared to no additional therapy or placebo in cancer patients (children and adults) receiving anthracyclines. DATA COLLECTION AND ANALYSIS: Two review authors independently performed the study selection, risk of bias assessment and data extraction including adverse effects. MAIN RESULTS: We identified RCTs for the eight cardioprotective agents N-acetylcysteine, phenethylamines, coenzyme Q10, a combination of vitamins E and C and N-acetylcysteine, L-carnitine, carvedilol, amifostine and dexrazoxane (mostly for adults with advanced breast cancer). All studies had methodological limitations and for the first seven agents there were too few studies to allow pooling of results. None of the individual studies showed a cardioprotective effect. The 10 included studies on dexrazoxane enrolled 1619 patients. The meta-analysis for dexrazoxane showed a statistically significant benefit in favour of dexrazoxane for the occurrence of heart failure (risk ratio (RR) 0.29, 95% CI 0.20 to 0.41). No evidence was found for a difference in response rate or survival between the dexrazoxane and control groups. The results for adverse effects were ambiguous. No significant difference in the occurrence of secondary malignancies was identified. AUTHORS' CONCLUSIONS: No definitive conclusions can be made about the efficacy of cardioprotective agents for which pooling of results was impossible. Dexrazoxane prevents heart damage and no evidence for a difference in response rate or survival between the dexrazoxane and control groups was identified. The evidence available did not allow us to reach any definite conclusions about adverse effects. We conclude that if the risk of cardiac damage is expected to be high, it might be justified to use dexrazoxane in patients with cancer treated with anthracyclines. However, clinicians should weigh the cardioprotective effect of dexrazoxane against the possible risk of adverse effects for each individual patient.

Parenteral anticoagulation in patients with cancer who have no therapeutic or prophylactic indication for anticoagulation.

BACKGROUND: Anticoagulation may improve survival in patients with cancer through an antitumor effect in addition to the perceived antithrombotic effect. OBJECTIVES: To evaluate the efficacy and safety of parenteral anticoagulants in patients with cancer with no therapeutic or prophylactic indication for anticoagulation. SEARCH STRATEGY: A comprehensive search included (1) an electronic search (February 2010) of the following databases: Cochrane Central Register of Controlled Trials (CENTRAL) Issue 1, 2010, MEDLINE, EMBASE and ISI the Web of Science; (2) handsearch of conference proceedings; (3) checking of references of included studies; and (4) use of the 'related citation' feature in PubMed. SELECTION CRITERIA: Randomized controlled trials (RCTs) assessing the benefits and harms of parenteral anticoagulation in patients with cancer but no therapeutic or prophylactic indication for anticoagulation. DATA COLLECTION AND ANALYSIS: Using a standardized form we extracted in duplicate data on methodological quality, participants, interventions and outcomes of interest including all-cause mortality, symptomatic thromboembolism, major bleeding, minor bleeding and quality of life (QoL). MAIN RESULTS: Of 8187 identified citations, nine RCTs enrolling 2857 patients fulfilled the inclusion criteria. In all included RCTs the intervention consisted of heparin (either unfractionated heparin or low molecular weight heparin). Overall, the effect of heparin therapy on mortality was not statistically significant at 12 months (risk ratio (RR) 0.93; 95% CI 0.85 to 1.02) but it was statistically significant at 24 months (RR 0.92; 95% CI 0.88 to 0.97). Heparin therapy was associated with a statistically and clinically important reduction in venous thromboembolism (RR 0.55; 95% CI 0.37 to 0.82). There were no statistically significant effects on major bleeding (RR 1.30; 95% CI 0.59 to 2.88), minor bleeding (RR 1.05; 95% 0.75 to 1.46) or QoL. The quality of evidence was high for symptomatic venous thromboembolism, moderate for mortality, major bleeding and minor bleeding, and low for QoL. AUTHORS' CONCLUSIONS: Heparin was associated with a significant reduction of death at 24 months but not 12 months. It was also associated with a reduction in venous thromboembolism but based on the RCTs in this review it had no significant effect on major bleeding, minor bleeding or QoL. Future research should further investigate the survival benefit of different types of anticoagulants in patients with different types and stages of cancer. The decision for a patient with cancer to start heparin therapy for survival benefit should balance the benefits and downsides and integrate the patient's values and preferences.

Ultra-radical (extensive) surgery versus standard surgery for the primary cytoreduction of advanced epithelial ovarian cancer.

BACKGROUND: Ovarian cancer is the sixth most common cancer among women and the leading cause of death in women with gynaecological malignancies. Opinions differ regarding the role of ultra-radical (extensive) cytoreductive surgery in ovarian cancer treatment.  OBJECTIVES: To evaluate the effectiveness and morbidity associated with ultra-radical/extensive surgery in the management of advanced stage ovarian cancer. SEARCH STRATEGY: We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 4), MEDLINE and EMBASE (up to November 2010). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) or non-randomised studies, analysed using multivariate methods, that compared ultra-radical/extensive and standard surgery in adult women with advanced primary epithelial ovarian cancer. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed whether potentially relevant studies met the inclusion criteria, abstracted data and assessed the risk of bias. One non-randomised study was identified so no meta-analyses were performed. MAIN RESULTS: One non-randomised study met our inclusion criteria. It analysed retrospective data for 194 women with stage IIIC advanced epithelial ovarian cancer who underwent either ultra-radical (extensive) or standard surgery and reported disease specific overall survival and perioperative mortality. Multivariate analysis, adjusted for prognostic factors, identified better disease specific survival among women receiving ultra-radical surgery, although this was not statistically significant (Hazard ratio (HR) = 0.64, 95% confidence interval (CI): 0.40 to 1.04). In a subset of 144 women with carcinomatosis, those who underwent ultra-radical surgery had significantly better disease specific survival than women who underwent standard surgery (adjusted HR = 0.64, 95% CI 0.41 to 0.98). Progression-free survival and quality of life (QoL) were not reported and adverse events were incompletely documented. The study was at high risk of bias. AUTHORS' CONCLUSIONS: We found only low quality evidence comparing ultra-radical and standard surgery in women with advanced ovarian cancer and carcinomatosis. The evidence suggested that ultra-radical surgery may result in better survival.  It was unclear whether there were any differences in progression-free survival, QoL and morbidity between the two groups. The cost-effectiveness of this intervention has not been investigated. We are, therefore, unable to reach definite conclusions about the relative benefits and adverse effects of the two types of surgery.In order to determine the role of ultra-radical surgery in the management of advanced stage ovarian cancer, a sufficiently powered randomised controlled trial comparing ultra-radical and standard surgery or well-designed non-randomised studies would be required.

Medical interventions for high grade vulval intraepithelial neoplasia.

BACKGROUND: Vulval intraepithelial neoplasia (VIN) is a pre-malignant condition of the vulval skin; its incidence is increasing in women under 50 years. VIN is graded histologically as low grade or high grade. High grade VIN is associated with infection with human papilloma virus (HPV) infection and may progress to invasive disease. There is no consensus on the optimal management of high grade VIN. The high morbidity and high relapse rate associated with surgical interventions call for a formal appraisal of the evidence available for less invasive but effective interventions for high grade VIN. OBJECTIVES: To evaluate the effectiveness and safety of medical interventions for high grade VIN. SEARCH STRATEGY: We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 3), MEDLINE and EMBASE (up to September 2010). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) that assessed medical interventions, in adult women diagnosed with high grade VIN. DATA COLLECTION AND ANALYSIS: Two review authors independently abstracted data and assessed risk of bias. Where possible the data were synthesised in a meta-analysis. MAIN RESULTS: Four trials met our inclusion criteria: three assessed the effectiveness of topical imiquimod versus placebo in women with high grade VIN; one examined low versus high dose indole-3-carbinol in similar women. Meta-analysis of three trials found that the proportion of women who responded to treatment at 5 to 6 months was much higher in the group who received topical imiquimod than in the group who received placebo (relative risk (RR) = 11.95, 95% confidence interval (CI) 3.21 to 44.51). A single trial showed similar results at 12 months in (RR = 9.10, 95% CI 2.38 to 34.77). Only one  trial reported adverse events, which were more common in the imiquimod group. One trial found no significant differences in quality of life (QoL) or body image between the imiquimod and placebo groups. AUTHORS' CONCLUSIONS: Imiquimod appears to be effective, but its safety needs further examination. Its use is associated with side effects which are tolerable, but more extensive data on adverse effects are required. Long term follow-up should be mandatory in view of the known progression of high grade VIN to invasive disease. Alternative medical interventions, such as cidofovir, should be explored.

Parenteral anticoagulation in patients with cancer who have no therapeutic or prophylactic indication for anticoagulation.

BACKGROUND: Anticoagulation may improve survival in patients with cancer through an antitumor effect in addition to the perceived antithrombotic effect. OBJECTIVES: To evaluate the efficacy and safety of parenteral anticoagulants in patients with cancer with no therapeutic or prophylactic indication for anticoagulation. SEARCH STRATEGY: A comprehensive search included (1) an electronic search (February 2010) of the following databases: Cochrane Central Register of Controlled Trials (CENTRAL) Issue 1, 2010, MEDLINE, EMBASE and ISI the Web of Science; (2) handsearch of conference proceedings; (3) checking of references of included studies; and (4) use of the 'related citation' feature in PubMed. SELECTION CRITERIA: Randomized controlled trials (RCTs) assessing the benefits and harms of parenteral anticoagulation in patients with cancer but no therapeutic or prophylactic indication for anticoagulation. DATA COLLECTION AND ANALYSIS: Using a standardized form we extracted in duplicate data on methodological quality, participants, interventions and outcomes of interest including all-cause mortality, symptomatic thromboembolism, major bleeding, minor bleeding and quality of life (QoL). MAIN RESULTS: Of 8187 identified citations, nine RCTs enrolling 2857 patients fulfilled the inclusion criteria. In all included RCTs the intervention consisted of heparin (either unfractionated heparin or low molecular weight heparin). Overall, the effect of heparin therapy on mortality was not statistically significant at 12 months (risk ratio (RR) 0.93; 95% CI 0.85 to 1.02) but it was statistically significant at 24 months (RR 0.92; 95% CI 0.88 to 0.97). Heparin therapy was associated with a statistically and clinically important reduction in venous thromboembolism (RR 0.55; 95% CI 0.37 to 0.82). There were no statistically significant effects on major bleeding (RR 1.30; 95% CI 0.59 to 2.88), minor bleeding (RR 1.05; 95% 0.75 to 1.46) or QoL. The quality of evidence was high for symptomatic venous thromboembolism, moderate for mortality, major bleeding and minor bleeding, and low for QoL. AUTHORS' CONCLUSIONS: Heparin was associated with a significant reduction of death at 24 months but not 12 months. It was also associated with a reduction in venous thromboembolism but based on the RCTs in this review it had no significant effect on major bleeding, minor bleeding or QoL. Future research should further investigate the survival benefit of different types of anticoagulants in patients with different types and stages of cancer. The decision for a patient with cancer to start heparin therapy for survival benefit should balance the benefits and downsides and integrate the patient's values and preferences.

Surgical interventions for high grade vulval intraepithelial neoplasia.

BACKGROUND: Vulval intraepithelial neoplasia (VIN) is a pre-malignant condition of the vulval skin. This uncommon chronic skin condition of the vulva is associated with a high risk of recurrence and the potential to progress to vulval cancer. The condition is complicated by its' multicentric and multifocal nature. The incidence of this condition appears to be rising particularly in the younger age group.There is a lack of consensus on the optimal surgical treatment method. However, the rationale for surgical treatment of VIN has been to treat symptoms and exclude underlying malignancy with the continued aim of preservation of vulval anatomy and function. Repeated treatments affect local cosmesis and cause psychosexual morbidity thus impacting on the patients' quality of life. OBJECTIVES: To evaluate the effectiveness and safety of surgical interventions for high grade VIN. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 3, 2010, Cochrane Gynaecological Cancer Group Trials Register, MEDLINE and EMBASE up to September 2010. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) that compared surgical interventions, in adult women diagnosed with high grade vulval intraepithelial neoplasia. DATA COLLECTION AND ANALYSIS: Two review authors independently abstracted data and assessed risk of bias. MAIN RESULTS: We found only one RCT which included 30 women that met our inclusion criteria and this trial reported data on carbon dioxide laser (CO(2) laser) versus ultrasonic surgical aspiration (USA).There was no statistically significant difference in the risk of disease recurrence after one year follow-up, pain, presence of scarring, dysuria or burning, adhesions, infection, abnormal discharge and eschar between women who received CO(2) laser and those who received USA. The trial lacked statistical power due to the small number of women in each group and the low number of observed events, but was at low risk of bias. AUTHORS' CONCLUSIONS: The included trial lacked statistical power due to the small number of women in each group and the low number of observed events. Therefore in the absence of reliable evidence regarding the effectiveness and safety of the two surgical techniques for the management of vulval intraepithelial neoplasia precludes any definitive guidance or recommendations for clinical practice.

Access of children with cerebral palsy to the physical, social and attitudinal environment they need: a cross-sectional European study.

PURPOSE: The UN Convention on the Rights of Persons with Disabilities requires states 'to ensure to persons with disabilities access, on an equal basis with others, to the physical environment, transportation, information and communications.' We explored whether this convention was respected for disabled children in Europe. METHOD: One thousand one-hundred and seventy-four children aged 8-12 years were randomly selected from population-based registers of children with cerebral palsy in eight European regions. 743 children joined the study; one further region recruited 75 children from multiple sources. Researchers visited these 818 children and administered the European Child Environment Questionnaire, which records parents' perceptions of availability of the physical, social and attitudinal environment needed in home, school and community. Multilevel, multivariable regression related child access on these domains to their impairments and socio-demographic characteristics. RESULTS: Children with more impaired walking ability had less access to the physical environment, transport and social support they needed than other children. They also experienced less favourable attitudes from family and friends. However, attitudes of teachers and therapists were similar for children with all levels of impairment. The access of children, across all impairment severities, to their needed environment showed significant variation between regions (p ≤ 0.0001), some regions consistently providing better access on most or all domains. CONCLUSION: European states need to substantially improve environmental access for disabled children in order to meet their obligations under UN Conventions. In some regions, many environmental factors should and realistically could be changed. Legislation and regulation should be directed to making this happen. Local environmental planners and health and social service providers should listen carefully to parents to address mismatches between policy intentions and parental experience.

Quantifying the physical, social and attitudinal environment of children with cerebral palsy.

PURPOSE: To develop an instrument to represent the availability of needed environmental features (EFs) in the physical, social and attitudinal environment of home, school and community for children with cerebral palsy. METHOD: Following a literature review and qualitative studies, the European Child Environment Questionnaire (ECEQ) was developed to capture whether EFs needed by children with cerebral palsy were available to them: 24, 24 and 12 items related to the physical, social and attitudinal environments, respectively. The ECEQ was administered to parents of 818 children with cerebral palsy aged 8-12 years, in seven European countries. A domain structure was developed using factor analysis. RESULTS: Parents responded to 98% of items. Seven items were omitted from statistical models as the EFs they referred to were available to most children who needed them; two items were omitted as they did not fit well into plausible domains. The final domains, based on 51 items, were: Transport, Physical - home, Physical - community, Physical - school, Social support - home, Social support - community, Attitudes - family and friends, Attitudes - teachers and therapists, Attitudes - classmates. CONCLUSION: ECEQ was acceptable to parents and can be used to assess both the access children with cerebral palsy have to the EFs that they need and how available individual EFs are.
