Psychological and physical activity training for older persons: who does not attend?

BACKGROUND: Interventions to promote successful aging include psychological and physical activity programs. Identification of determinants of attendance of older persons may be useful to develop strategies to improve attendance. For physical activity programs determinants of attendance have been investigated extensively. For psychological programs hardly any knowledge is available. Determinants of attendance at psychological and physical activity programs have never been investigated simultaneously. OBJECTIVE: To identify demographic, physical and psychological determinants of attendance of older subjects following multifaceted psychological training - aimed at promoting active social participation - and physical activity training and to compare the variation of these determinants between the two training programs. METHOD: 118 subjects aged 65-92 years were randomized over psychological and physical activity training. Determinants of attendance were obtained at pretest with questionnaires and performance-based tests. RESULTS: Mean attendance was 62%. Attendance was not related to type of program. Having chronic diseases facilitated attendance in the psychological training group and limited attendance in the physical activity training group. Low and high levels of Activities of Daily Living performance (ADLs) and walking endurance were related to a high attendance in the psychological training group. A low level of activities of daily living (ADL) and a low walking endurance were related to a low attendance in the physical activity training group. For both training groups, persons living with a partner had higher attendance rates than persons living alone, and persons with a low level of anxiety had higher attendance rates than persons with a moderate or a high level of anxiety. CONCLUSION: Psychological training may be more suitable for frail older persons with chronic diseases, low ADL levels and low walking endurance than physical activity training, and may help to prepare such persons for physical activity.     

Perinatal risk factors interacting with catechol O‐methyltransferase and the serotonin transporter gene predict ASD symptoms in children with ADHD

Background: Symptoms of autism spectrum disorder (ASD) and attention‐deficit/hyperactivity disorder (ADHD) often co‐occur. Given the previously found familiality of ASD symptoms in children with ADHD, addressing these symptoms may be useful for genetic association studies, especially for candidate gene findings that have not been consistently replicated for ADHD. Methods: We studied the association of the catechol O‐methyltransferase (COMT) Val158Met polymorphism and the serotonin transporter (SLC6A4/SERT/5‐HTT) 5‐HTTLPR insertion/deletion polymorphism with ASD symptoms in children with ADHD, and whether these polymorphisms would interact with pre‐ and perinatal risk factors, i.e., maternal smoking during pregnancy and low birth weight. Analyses were performed using linear regression in 207 Dutch participants with combined type ADHD of the International Multicenter ADHD Genetics (IMAGE) study, and repeated in an independent ADHD sample (n = 439) selected from the TRracking Adolescents’ Individual Lives Survey (TRAILS). Dependent variables were the total and subscale scores of the Children’s Social Behavior Questionnaire (CSBQ). Results: No significant main effects of COMT Val158Met, 5‐HTTLPR, maternal smoking during pregnancy and low birth weight on ASD symptoms were found. However, the COMT Val/Val genotype interacted with maternal smoking during pregnancy in increasing stereotyped behavior in the IMAGE sample (p = .008); this interaction reached significance in the TRAILS sample after correction for confounders (p = .02). In the IMAGE sample, the 5‐HTTLPR S/S genotype interacted with maternal smoking during pregnancy, increasing problems in social interaction (p = .02), and also interacted with low birth weight, increasing rigid behavior (p = .03). Findings for 5‐HTTLPR in the TRAILS sample were similar, albeit for related CSBQ subscales. Conclusions: These findings suggest gene–environment interaction effects on ASD symptoms in children with ADHD.     

Lower sensitivity of screening mammography after previous benign breast surgery

Few data are available on the effect of previous benign breast surgery on screening mammography accuracy. We determined whether sensitivity of screening mammography and tumor characteristics are different for women with and without previous benign breast surgery. We included a consecutive series of 317,398 screening mammograms of women screened between 1997 and 2008. During 2-year follow-up, clinical data, breast imaging, biopsy and surgery reports were collected from women with screen-detected or interval breast cancers. Screening sensitivity, tumor biology and tumor stages were compared between 168 women with breast cancer and prior ipsilateral benign breast surgery and 2,039 women with breast cancer but without previous ipsilateral, benign breast surgery. The sensitivity of screening mammography was significantly lower for women with prior surgery [64.3% (108/168) versus 73.4% (1,496/2,039), p = 0.01]. The concomitant increased interval cancer risk remained significant after logistic regression adjustment for age and breast density (OR = 1.5, 95% CI: 1.1-2.1). Comparing screen-detected cancers in women with and without prior breast surgery, no significant differences in estrogen receptor status (p = 0.56), mitotic activity (p = 0.17), proportions of large (T2+) tumors (p = 0.6) or lymph node positive tumors (p = 0.4) were found. Also for interval cancers, no differences were found in estrogen receptor status (p = 0.41), mitotic activity (p = 0.39), proportions of large tumors (p = 0.9) and lymph node positive tumors (p = 0.5) between women with and without prior breast surgery. We conclude that sensitivity of screening mammography is significantly lower in women with previous benign breast surgery than without, but tumor characteristics are comparable both for screen detected cancers and interval cancers.     

Quality of urological cancer diagnoses in the Danish National Registry of Patients

Valid and up-to-date data on cancer diagnoses are needed for clinical quality monitoring and epidemiological research. The Danish National Registry of Patients (DNRP) is continuously updated, recording all Danish hospital contacts including cancer diagnoses. The Danish Cancer Registry (DCR) is updated once a year and includes quality control of diagnoses. We compared the quality of urological cancer diagnoses in the DNRP with the DCR to assess whether data in an administrative hospital registry are valid compared with data from a well-established cancer registry. We identified 60 434 incident urological cancer cases in the DNRP and/or the DCR from 2001 to 2009. Completeness and the positive predictive value (PPV) of urological cancer registration in the DNRP were estimated using the DCR as the reference standard. To examine the impact of potential misclassification, we computed mortality estimates for urological cancer patients in each registry. Because DCR registration procedures changed in 2004, the periods 2001-2003 and 2004-2009 were analyzed separately. In 2004-2009, the overall completeness and PPV of urological cancer registration in the DNRP were 94.9% (95% confidence interval: 94.7-95.2%) and 86.6% (95% confidence interval: 86.3-86.9%), respectively, compared with diagnoses recorded in the DCR. Completeness and PPV of cancer registration in the DNRP varied between cancer subgroups. In 2001-2003, both completeness and PPV in the DNRP were slightly lower compared with 2004-2009. Mortality estimates in patients registered in the DNRP and the DCR varied slightly. The DNRP could be a valuable source of data for clinical quality monitoring and epidemiological research for some urological cancers, especially when current data are essential.     

Phone and e-mail counselling are effective for weight management in an overweight working population: a randomized controlled trial

Background  

The work setting provides an opportunity to introduce overweight (i.e., Body Mass Index ≥ 25 kg/m²) adults to a weight management programme, but new approaches are needed in this setting. The main purpose of this study was to investigate the effectiveness of lifestyle counselling by phone or e-mail on body weight, in an overweight working population. Secondary purposes were to establish effects on waist circumference and lifestyle behaviours, and to assess which communication method is the most effective.
