The prevalence of physical, sexual and mental abuse among adolescents and the association with BMI status
<p>Abstract</p> <p>Background</p> <p>Studies among adults show an association between abuse and Body Mass Index (BMI) status. When an aberrant BMI status as a consequence of abuse is already prevalent in adolescence, early detection and treatment of abuse might prevent these adolescents from developing serious weight problems and other long-term social, emotional and physical problems in adulthood. Therefore, this study investigated the prevalence of physical, sexual and mental abuse among adolescents and examined the association of these abuse subtypes with BMI status.</p> <p>Methods</p> <p>In total, data of 51,856 secondary school students aged 13–16 who had completed a questionnaire on health, well-being and lifestyle were used. BMI was classified into four categories, underweight, normal weight, overweight and obesity. Adolescents reported if they had ever been physically, sexually or mentally abused. Crude and adjusted General Estimation Equation (GEE) analyses were performed to investigate the association between abuse subtypes and BMI status. Analyses were adjusted for ethnicity and parental communication, and stratified for gender and educational level.</p> <p>Results</p> <p>Eighteen percent of the adolescents reported mental abuse, 7% reported sexual abuse, and 6% reported physical abuse. For underweight, overweight and obese adolescents these percentages were 17%, 25%, and 44%; 7%, 8%, and 16%; and 6%, 8%, 18% respectively. For the entire population, all these subtypes of abuse were associated with being overweight and obese (OR=3.67, 1.79 and 1.50) and all but sexual abuse were associated with underweight (OR=1.21 and 1.12). Stratified analyses showed that physical and sexual abuse were significantly associated with obesity among boys (OR=1.77 and 2.49) and among vocational school students (OR=1.60 and 1.69), and with underweight among girls (OR=1.26 and 0.83).</p> <p>Conclusion</p> <p>Mental abuse was reported by almost half of the obese adolescents and associated with underweight, overweight and obesity. Longitudinal analyses are recommended to explore the causality of and the mechanisms explaining this association between abuse and overweight.</p
Loss of Ep-CAM (CO17-1A) expression predicts survival in patients with gastric cancer
Preoperative staging of gastric cancer is difficult and not optimal. The TNM stage is an important prognostic factor, but it can only be assessed reliably after surgery. Therefore, there is need for additional, reliable prognostic factors that can be determined preoperatively in order to select patients who might benefit from (neo) adjuvant treatment. Expression of immunohistochemical markers was demonstrated to be associated with tumour progression and metastasis. The expression of p53, CD44 (splice variants v5, v6 and v9), E-cadherin, Ep-CAM (CO17-1A antigen) and c-erB2/neu were investigated in tumour tissues of 300 patients from the Dutch Gastric Cancer Trial, investigating the value of extended lymphadenectomy compared to that of limited lymphadenectomy). The expression of tumour markers was analysed with respect to patient survival. Patients without loss of Ep-CAM-expression of tumour cells (19%) had a significantly better 10-year survival (P<0.0001) compared to patients with any loss: 42% (s.e.=7%) vs 22% (s.e.=3%). Patients with CD44v6 (VFF18) expression in more than 25% of the tumour cells (69% of the patients) also had a significantly better survival (P=0.01) compared to patients with expression in less than 25% of the tumour cells: 10 year survival rate of 29% (s.e.=3%) vs 19% (s.e.=4%). The prognostic value of both markers was stronger in stages I and II, and independent of the TNM stage. Ep-CAM and CD44v6-expression provides prognostic information additional to the TNM stage. Loss of Ep-CAM-expression identifies aggressive tumours especially in patients with stage I and II disease. This information may be helpful in selecting patients suitable for surgery or for additional treatment pre- or postoperatively
Expression of high p53 levels in colorectal cancer: a favourable prognostic factor
The expression of p53 protein was examined in a series of 111 colorectal cancer adenocarcinomas with a long follow-up. A quantitative luminometric immunoassay (LIA) was used for the measurement of wild-type and mutant p53 protein in extracts from colorectal tumour cytosols, p53 being detected in 42% of the samples (range 0.0–52 ng mg−1). Using an arbitrary cut-off value of 2.7 ng mg−1, 25% of the tumours were classified as manifesting high p53 levels. There was no association of p53 expression with patient age, sex, serum preoperative carcinoembryonic antigen (CEA) levels, tumour site and size, nodal status or TNM stage. Significant and independent correlation was found to exist between high p53 levels and prolonged disease-free survival (P = 0.05) at a median follow-up of 60 months. This survival advantage was most apparent among stage III cancer patients. The results from this study would suggest that expression of high p53 levels appear to be useful in selecting a group of colorectal cancer patients with a better prognosis. © 1999 Cancer Research Campaig
Refractory coeliac disease type I and II; Pilot-treatment with azathioprine and predinison
Cardiac output measured by uncalibrated arterial pressure waveform analysis by recently released software version 3.02 versus thermodilution in septic shock
To evaluate the 3.02 software version of the FloTrac/Vigileo (TM) system for estimation of cardiac output by uncalibrated arterial pressure waveform analysis, in septic shock. Nineteen consecutive patients in septic shock were studied. FloTrac/Vigileo (TM) measurements (COfv) were compared with pulmonary artery catheter thermodilution-derived cardiac output (COtd). The mean cardiac output was 7.7 L min(-1) and measurements correlated at r = 0.53 (P 10 % in both COtd and COfv (n = 46) were in the same direction. Eighty-five percent of the measurements were within the 30A degrees aEuro"330A degrees of the polar axis. COfv with the latest software still underestimates COtd at low SVR in septic shock. The tracking capacities of the 3.02 software are moderate-good when clinically relevant changes are considered
Randomised phase III study of biweekly 24-h infusion of high-dose 5FU with folinic acid and oxaliplatin versus monthly plus 5-FU/folinic acid in first-line treatment of advanced colorectal cancer
Background: A phase III study was started to compare oxaliplatin/5FU/LV in the first-line with bolus FU/LV in metastatic colorectal cancer. Patients and methods: 302 patients were randomised and received bolus 5-FU 425 mg/m(2) day 1-5, FA 20 mg/m(2) day 1-5, q 4 wk or oxaliplatin 85 mg/m(2), 2 h-infusion, FA 200 mg/m(2), 1-h infusion. 5-FU 2600 mg/m(2), 24-h infusion day 1, q 2 wk. The primary endpoint was response rate (RR). Results: The median follow-up is 31.8 months, 90.4% of the patients have died. Confirmed RR, progression free survival (PFS; months) and median overall survival (OS; months) in 5FU/LV versus 5FU/LV/oxaliplatin were respectively 18.5% versus (vs) 33.8% (P = 0.004), 5.6 vs 6.7 (P = 0.016) and 13.3 vs 13.8 (P = 0.619). In the 5FU/LV/oxaliplatin arm less grade 3/4 toxicity was measured for diarrhoea, stomatitis, an increase in idiosyncratic side effects and neurosensory events compared with 5FU/LV. The quality of life (QOL) was equal in both arms. Second line treatment was given in 62% of the patients, crossover of 5FU/LV to 5FU/LV/oxaliplatin occurred in 14%. Conclusions: Oxaliplatin in the first-line resulted in an increased RR and PFS with less grade 3/4 mucositis/diarrhoea compared with 5FU/LV alone. Idiosyncratic side effects deserve attention with oxaliplatin. Despite a low treatment cross over rate, OS in both groups was comparable
