Results of a Rural School-Based Peer-Led Intervention for Youth: Goals for Health

BACKGROUND: School-based interventions are critical for enhancing the health of youth. The Goals for Health (GFH) school-based project was a goal-setting and life-skills intervention conducted in rural areas to increase self-efficacy, knowledge, and positive behaviors related to healthy eating. The intervention was peer-led with high school students teaching health and life skills to sixth-grade students. The purpose of this study was to examine the impact of the GFH school-based program on healthy eating outcomes related to self-efficacy, attitudes, knowledge, and behavior, and to examine the impact of quality of program implementation on the above outcomes. METHODS: Twenty-three rural schools in Virginia (15) and New York (8) participated in the study. Twelve of the schools were intervention schools that received the 12-week GFH program. The remaining 11 were wait-list control schools. Sixth graders (n = 2120 baseline) from all schools were surveyed at 4 time points (preintervention, postintervention, 1 and 2 year follow-up). RESULTS: Results included significant change patterns across the 4 assessment points in the predicted direction for healthy eating-related self-efficacy and fat and fiber knowledge. No significant change patterns were found at follow-up for fat, fiber, or fruit and vegetable intake. Results also indicated differences across gender and ethnicity and significant findings related to quality of implementation. CONCLUSIONS: Future interventions need to provide opportunities to practice healthy living skills over an extended period of time, include components that focus on contextual change in the school and the family, and monitor program implementation.     

Clinicopathologic evaluation of subgroups of diffuse large B cell lymphoma by immunohistochemistry

Diffuse large B cell lymphoma (DLBCL) has become an emerging epidemic in recent years. Striking heterogeneity in its clinical, biological and treatment responses prompted us to identify variation in our study group. The aim was to classify the DLBCL into prognosis-based subgroups according to the WHO classification and to evaluate their relation to clinical parameters (age, gender, anatomic location and B symptoms), as well as bcl 2 and Ki 67 status. Patients and Methods: A cross sectional study was carried out on 42 DLBCL patients, classified histologically and immunophenotypically into germinal center B cell like (GCB) or non-GCB type. Immunohistochemistry (IHC) was performed using antibodies against CD 10, MUM-1 and bcl 6; additionally anti-apoptotic protein bcl 2 and proliferative marker Ki 67 (using cutoff value of 70%) were also assayed by IHC. Results: Of the total 27/42 (64%) were males and 15/42 (36%) females, with a mean age of 44.1±15 years. 15/42 (36%) cases were of GCB type as compared to 27/42 (64%) of non GCB type. Extranodal involvement and B symptoms were seen in 18/27 (66.6%) and 20/27(74%) of the non GCB type, whereas bcl 2 protein expression and Ki 67 proliferative index (PI) <70% were each noted in 22/27 (81.4%). Conclusion: We document an astonishingly high number of non-GCB type DLBCL in our population. It is alarming to see such an aggressive tumor proliferating in our region. Significant association of non-GCB type with extranodal origin, B symptoms and low Ki 67 PI (<70%) is another concern.     

Knowledge gap of recommendations in ACOG practice bulletins: a survey of members of the Central Association of Obstetricians and Gynecologists

The purpose of this survey was to assess the knowledge gap of recommendations in practice bulletins (PBs). A survey consisting of three questions for 12 selected PBs (six obstetric and six gynecologic) was developed and sent to members of the Central Association. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Of the 385 active members, 100 (26%) returned the survey. The overall correct score was 49%. Respondents were significantly more likely to know recommendations in obstetric PBs (60%) than gynecologic PBs (39%; OR 2.45, 95% CI 2.12-2.81). Maternal-fetal medicine sub-specialists (n=27), compared with obstetricians-gynecologists (n=66), did significantly better with obstetric PBs (67% vs. 59%; OR 1.42, 95% CI 1.32-1.77) and substantially worse with gynecologic topics (34% vs. 39%; OR 0.79, 95% CI 0.63-0.98). In conclusion, since members of the Central Association have a substantial knowledge gap, there are ample opportunities to educate and reinforce PB recommendations.     

Classification of hand eczema: clinical and aetiological types. Based on the guideline of the Danish Contact Dermatitis Group

Background. No generally accepted classification scheme for hand eczema exists. The Danish Contact Dermatitis Group recently developed a guideline defining common clinical types and providing criteria for aetiological types. Objectives. To test the concepts of this guideline in a group of hand eczema patients. Methods. Seven hundred and ten hand eczema patients were included from seven dermatology clinics in Denmark. The hand eczema was classified into one of five clinical types, with standard photographs as reference. The severity was scored by the physician, who also made a final aetiological diagnosis. Results. Irritant contact dermatitis was most frequent in chronic, dry fissured hand eczema (44.3%), pulpitis (41.7%), and nummular hand eczema (40.9%), whereas allergic contact dermatitis dominated in vesicular types of hand eczema, with recurrent (35%) and few (24.2%) eruptions. Hyperkeratotic palmar hand eczema was the only clinical type that constituted a distinct subgroup; it was found most frequently in older men and had the strongest relationship, although not significant, with non‐specific dermatitis. Conclusions. The relationship between clinical type of hand eczema and aetiological diagnosis fitted with general experience, but no simple relationship was found. This emphasizes that patch testing and exposure analysis are mandatory. Hyperkeratotic palmar hand eczema was identified as a distinct clinical subtype.     

Contact allergy to methyldibromo glutaronitrile--data from a 'front line' network

The preservative methyldibromo glutaronitrile (MDBGN) has caused an epidemic of contact allergy in Europe. However, most data concerning contact allergy comes from hospital departments of dermatology. As a part of the primary health care sector, Danish dermatologists in private practice provide the front line of care for patients with skin diseases. Data from this source may therefore better reflect trends in the general population than material from hospital departments of dermatology. In this study, the frequency of MDBGN allergy and the characteristics of patients seen by dermatologists in private practice were studied. In 1 year, 2146 patients were patch tested by the participating dermatologists from 4 clinics in various parts of Denmark. 5% (110) had positive patch tests to MDBGN, with no difference between the sexes. After adjustment was made for other background variables, multivariate analysis using logistic regression showed a significant association between hand eczema and MDBGN allergy (OR 2.5, P < 0.001). In 53 cases (52.4%), the patch test reaction to MDBGN was judged to be of current relevance. Creams and lotions accounted for 31% of the identified causative products and liquid soaps for 23%. It is concluded that contact allergy to MDBGN is frequent among patients seen by dermatologists in private practice. This is consistent with results from hospital departments of dermatology in Europe and indicates a general trend and ongoing epidemic in the general population. The significant relationship between hand eczema and MDBGN allergy is of concern, and the finding that wash-off products, especially liquid soaps, play a significant role in MDBGN allergy calls for a revision of the safety assessment of MDBGN in wash-off products.     

K-ras alterations in Danish ovarian tumour patients. From the Danish "Malova" Ovarian Cancer study

OBJECTIVE: Activation of ras oncogenes has been demonstrated in ovarian tumours. All the reported studies are based on a relatively small number of patients and the results therefore remain a subject of debate. METHODS: In this study, we analyzed the presence of mutations at codons 12 and 13 of the K-ras gene in 165 Danish women with ovarian tumours, including 138 invasive ovarian cancers and 27 borderline ovarian tumours, using a restriction fragment length polymorphism-polymerase chain reaction technique and evaluated whether such alterations were associated with the clinicopathological parameters of the patients and survival. RESULTS: K-ras codon 12 gene mutations were found in 8.7% of ovarian cancer patients and in 14.8% of the borderline ovarian tumour patients. A K-ras codon 13 gene mutation was found in 1.5% of ovarian cancer patients. K-ras mutations were found with a significantly higher frequency in mucinous tumours compared to serous tumours (P = 0.011). CONCLUSIONS: Mutation frequency was correlated with the histological type of tumour, but not with stage, radicality of operation, and age. Furthermore, no significant difference in survival was demonstrated between patients with or without K-ras mutation, neither in the univariate nor in the multivariate survival analyses.
