Self-reporting and measurement of body mass index in adolescents: refusals and validity, and the possible role of socioeconomic and health-related factors

BACKGROUND
Body mass index assessment using self-reported height and weight (BMIsr) can encounter refusals and under/over-reporting while for assessment with measured data (BMIm) refusals can be more frequent. This could relate to socioeconomic and health-related factors. We explored these issues by investigating numerous potential factors: gender, age, family structure, father's occupation, income, physical/sports activity, subjective weight perception, school performance, unhealthy behaviours, physical/psychological health, social relationships, living environment, having sustained violence, sexual abuse, and involvement in violence.


METHODS
The sample included 1559 adolescents from middle schools in north-eastern France. They completed a questionnaire including socioeconomic and health-related data, self-reported height/weight, measured height/weight, and weight perception (participation rate 94%). Data were analysed using logistic regression models.


RESULTS
BMIsr encountered under-reporting (with change in BMI category, 11.8%), over-reporting (6.0%), and reporting refusals (3.6%). BMIm encountered more numerous refusals (7.9%). Reporting refusal was related to living with a single parent, low school performance, lack of physical/sports activity, sustained violence, poor psychological health, and poor social relationships (gender/age-adjusted odds ratios 1.95 to 2.91). Further to these factors, measurement refusal was related to older age, having divorced/separated parents, a father being a manual worker/inactive, insufficient family income, tobacco/cannabis use, involvement in violence, poor physical health, and poor living environment (1.30 to 3.68). Under-reporting was related to male gender, involvement in violence, poor psychological health, and overweight/obesity (as assessed with BMIm) (1.52 to 11). Over-reporting was related to male gender, younger age, alcohol consumption, and underweight (1.30 to 5.35). Weight perception was linked to reporting refusals and under/over-reporting, but slightly linked to measurement refusal. The contributions of socioeconomic and health-related factors to the associations of weight perception with reporting refusal and under/over-reporting ranged from -82% to 44%. There were substantial discrepancies in the associations between socioeconomic/health-related factors and overweight/obesity assessed with BMIsr and BMIm.


CONCLUSIONS
BMIsr and BMIm were affected by numerous biases related to vulnerability which were also obesity risk factors. BMIsr encountered under/over-reporting which were related to some socioeconomic and health-related factors, weight perception, and BMIm. BMIm was more affected by refusals than BMIsr due to socioeconomic and health-related factors. Further research is needed.

ACKNOWLEDGMENTS We appreciate the support our data collections have received from the Kong University in China. We also acknowledge the participants who gave us useful feedback at the HCI International 2007 workshop and those who gave us feedback on the paper at a presentation at the University College Dublin, Spring 2008. Finally, we appreciate the insightful feedback and reviews and contributions to the literature from ABSTRACT Social computing technologies typically have multiple features that allow users to reveal their personal information to other users. Such self-disclosure (SD) behavior is generally considered positive and beneficial in interpersonal communication and relationships. Using a newly proposed model based on social exchange theory, this paper investigates and empirically validates the relationships between SD technology use and culture. In particular, we explore the effects of culture on information privacy concerns and the desire for online interpersonal awareness, which influence attitudes toward, intention to use, and actual use of SD technologies. Our model was tested using arguably the strongest social computing technology for online self-disclosure—instant messaging (IM)—with users from China and the US. Our findings reveal that cross-cultural dimensions are significant predictors of information privacy concerns and desire for online awareness, which were, in turn, found to be predictors of attitude toward, intention to use, and actual use of IM. Overall, our proposed model is applicable to both cultures. Our findings help enhance the theoretical understanding of the effects of culture and privacy concerns on SD technologies, and provide practical suggestions for developers of SD technologies, such as …
Immediate effects of osteopathic manipulative treatment in elderly patients with chronic obstructive pulmonary disease.

CONTEXT
Osteopathic manipulative treatment (OMT) has long been advocated for patients with respiratory disorders, but little definitive evidence exists to support its use in this population.


OBJECTIVE
To investigate the immediate effect of OMT on pulmonary function parameters in elderly subjects with chronic obstructive pulmonary disease.


METHODS
Subjects aged 65 years or older with a forced expiratory volume in 1 second to forced vital capacity ratio of less than 70% were recruited and randomly assigned to receive either OMT or sham therapy. The OMT protocol consisted of seven standardized osteopathic manipulative techniques, while the sham therapy protocol comprised light touch applied to the same anatomic regions and for the same duration (20 min). All subjects received baseline and posttreatment pulmonary function testing. A telephone survey was conducted 1 day after the intervention to collect subjective feedback and assess the success of blinding protocols.


RESULTS
Of the 35 study participants, 18 were randomly assigned to the OMT group and 17 to the sham group. Compared with the sham group, the OMT group showed a statistically significant decrease in the forced expiratory flow at 25% and 50% of vital capacity and at the midexpiratory phase; the expiratory reserve volume; and airway resistance. The OMT group also had a statistically significant increase in the residual volume, total lung capacity, and the ratio of those values compared with the sham group. Most subjects (82%, OMT group; 65%, sham group) reported breathing better after receiving their treatment. Only 53% of subjects in the OMT group and 41% in the sham group correctly guessed their group assignment.


CONCLUSION
Results suggest an overall worsening of air trapping during the 30 minutes immediately following one multitechnique OMT session relative to the sham group.
An investigation of carbon dioxide capture by chitin acetate/DMSO binary system.

Chitin is considered to be the second most abundant naturally-occurring polysaccharide. Also, dimethyl sulfoxide (DMSO) is the second highest dielectric constant polar solvent after water. Despite the low solubility of chitin in common organic solvents, and due to its high nitrogen content, it may serve as a potential scrubbing agent "wet scrubbing" for carbon dioxide (CO2) capturing as an alternative to monoethanolamine "renewables for renewables approach". Briefly, a detailed investigation for the utilization of low molecular weight, chitin-acetate (CA) in DMSO for the capturing of CO2 is reported. As carbonation process takes place, the formation of ionic alkylcarbonate was confirmed throughout spectroscopic and computational studies. Supramolecular chemisorption was proven throughout (1)H Nuclear Magnetic Resonance ((1)H NMR) together with the absence of sorption of CO2 by the monomeric repeating unit, glucosamine hydrochloride. Further, Density Functional Theory (DFT) calculations supported the formation of the CA/CO2 adduct through a newly formed supramolecular ionic interaction and hydrogen bonding along the oligosaccharide backbone between the neighboring ammonium ion and hydroxyl functional groups. The sorption capacity was measured volumetrically within an in situ Attenuated Total Reflectance-Fourier Transform Infrared coupled (in situ ATR-FTIR) autoclave at 25.0°C, and 4.0bar CO2, with a maximum sorption capacity of 3.63 [Formula: see text] /gsorbent at 10.0% (w/v).
Effects of false-positive prostate cancer screening results on subsequent prostate cancer screening behavior.

OBJECTIVES
Little is known about screening behavior following a false-positive prostate cancer screening result, which we have defined as a screening result with "abnormal/suspicious" labeling that did not result in a prostate cancer diagnosis within 14 months. The purpose of this analysis was to examine whether age, race, education, or previous false-positive prostate cancer screening results via prostate-specific antigen or digital rectal exam predict decision to obtain subsequent prostate cancer screening.


METHODS
Data were drawn from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. The study sample consisted of 2,290 older men (mean age, 62.8 years; range, 55-75 years) who had false-positive (n = 318) or negative (n = 1,972) prostate-specific antigen or digital rectal exam baseline prostate cancer screening results. Multivariable logistic regression was used to assess the effect of false-positive results on subsequent prostate cancer screening behavior, adjusting for all covariates.


RESULTS
The multivariable model showed that being African American (P = 0.016), and having a high school education or less (P = 0.007), having a previous false-positive prostate cancer screening result (P < 0.001), were predictive of not returning for prostate cancer screening in the following screening trial year.


CONCLUSION
The study results highlight the importance of shared decision making between patients and their providers regarding the risks and benefits of prostate cancer screening, and follow-up options for abnormal prostate cancer screening results. Shared decision making may be especially important for African American men, whom prostate cancer disproportionately affects.
What is abnormal uterine descent on translabial ultrasound?

Ultrasound is increasingly used in evaluating women with pelvic floor dysfunction, including quantification of pelvic organ prolapse (POP). The aim of this study was to define the optimal cutoff for uterine descent on translabial ultrasound (TLUS) to predict symptoms of prolapse. This was a retrospective study of patients seen for lower urinary tract symptoms and/or POP at a tertiary urogynecological center. All patients underwent a standardized interview, 4D TLUS and the International Continence Society Pelvic Organ Prolapse Quantification system (ICS POP-Q) assessment. Pelvic organ descent on US was measured relative to the posteroinferior margin of the symphysis pubis (SP) on maximum Valsalva. Receiver operator characteristic (ROC) statistics was used to determine the optimal cutoff. We assessed 538 data sets. Mean patient age was 53 years (range 18–88). Prolapse symptoms were reported by 263 (49 %). Clinically significant POP, i.e., ICS POP-Q  stage ≥2 was found in 74.5 %. This comprised a cystocele in 322, uterine prolapse in 63, enterocele in ten, and rectocele in 280 women. On TLUS, mean uterine position on Valsalva was 14.3 mm above the SP. Prolapse symptoms were strongly associated with uterine descent (20.7 mm vs 7.6 mm, P < 0.001). Using ROC statistics with and without excluding women with a dominant prolapse in other compartments, +15 mm was found to be the optimal cutoff for predicting symptoms of prolapse, with areas under the curve of 0.68 and 0.74, respectively. An optimal cutoff to predict prolapse symptoms due to uterine descent is a cervix descending to 15 mm above the symphysis pubis on maximum Valsalva.

Use and misuse in the application of the phytoplankton functional classification: a critical review with updates

Since its publication, the article ‘Towards a functional classification of the freshwater phytoplankton’ (Reynolds et al., J Plankton Res 24: 417–428, 2002), has attracted the attention of dozens of phytoplankton ecologists worldwide. These numerous applications of the functional classification to describe phytoplankton patterns in various aquatic ecosystems allowed the recognition of some uncertain features of this concept originating from various reasons. In this article, we attempt to facilitate the application of the functional classification, by providing a detailed description of the typical misplacements and by modifying some of the original habitat templates and species allocations. Furthermore, we discuss in this review those coda that were additionally described after the publication of the original article, and attempt giving an overview, as complete as possible, of the state of art.
A problem-oriented and rule-based component repository

Repository-based component reuse is an important technique for raising the eciency of software development. Traditional approaches focus only on repository organisation and retrieval techniques. This paper proposes a problem-oriented component reuse framework through incorporating a problem-solving mechanism with the traditional component repository. The framework improves the traditional approaches in two aspects. Firstly, the reuse is promoted from the component level to the problem-solving level. User is encouraged to concentrate on the problem description and solving problem through top-down re®nement rather than plunge into the technique details at the beginning. Secondly, the environment evolution during running the candidate components for composing an application is simulated through case-based rule reasoning. The candidate components are dynamically checked before composing an application system. We have designed a model base system for the application in scienti®c computing ®eld based on the framework. The application and analysis show the approach feasible. Ó 2000 Elsevier Science Inc. All rights reserved.

Au th or ' s pe rs on al co py Evidence for publication bias in video game violence effects literature : A meta-analytic review

Violence in video games has come under increasing research attention over the past decade. Researchers in this area have suggested that violent video games may cause aggressive behavior among players. However, the state of the extant literature has not yet been examined for publication bias. The current meta-analysis is designed to correct for this oversight. Results indicated that publication bias does exist for experimental studies of aggressive behavior, as well as for non-experimental studies of aggressive behavior and aggressive thoughts. Research in other areas, including prosocial behavior and experimental studies of aggressive thoughts were less susceptible to publication bias. Moderator effects results also suggested that studies employing less standardized and reliable measures of aggression tended to produce larger effect sizes. Suggestions for future violent video game studies are provided. © 2007 Elsevier Ltd. All rights reserved.
MicroRNA expression array identifies novel diagnostic markers for conventional and oncocytic follicular thyroid carcinomas.

OBJECTIVE
The most difficult thyroid tumors to be diagnosed by cytology and histology are conventional follicular carcinomas (cFTCs) and oncocytic follicular carcinomas (oFTCs). Several microRNAs (miRNAs) have been previously found to be consistently deregulated in papillary thyroid carcinomas; however, very limited information is available for cFTC and oFTC. The aim of this study was to explore miRNA deregulation and find candidate miRNA markers for follicular carcinomas that can be used diagnostically.


DESIGN
Thirty-eight follicular thyroid carcinomas (21 cFTCs, 17 oFTCs) and 10 normal thyroid tissue samples were studied for expression of 381 miRNAs using human microarray assays. Expression of deregulated miRNAs was confirmed by individual RT-PCR assays in all samples. In addition, 11 follicular adenomas, two hyperplastic nodules (HNs), and 19 fine-needle aspiration samples were studied for expression of novel miRNA markers detected in this study.


RESULTS
The unsupervised hierarchical clustering analysis demonstrated individual clusters for cFTC and oFTC, indicating the difference in miRNA expression between these tumor types. Both cFTCs and oFTCs showed an up-regulation of miR-182/-183/-221/-222/-125a-3p and a down-regulation of miR-542-5p/-574-3p/-455/-199a. Novel miRNA (miR-885-5p) was found to be strongly up-regulated (>40-fold) in oFTCs but not in cFTCs, follicular adenomas, and HNs. The classification and regression tree algorithm applied to fine-needle aspiration samples demonstrated that three dysregulated miRNAs (miR-885-5p/-221/-574-3p) allowed distinguishing follicular thyroid carcinomas from benign HNs with high accuracy.


CONCLUSIONS
In this study we demonstrate that different histopathological types of follicular thyroid carcinomas have distinct miRNA expression profiles. MiR-885-5p is highly up-regulated in oncocytic follicular carcinomas and may serve as a diagnostic marker for these tumors. A small set of deregulated miRNAs allows for an accurate discrimination between follicular carcinomas and hyperplastic nodules and can be used diagnostically in fine-needle aspiration biopsies.
Mesotherapy using dutasteride-containing preparation in treatment of female pattern hair loss: photographic, morphometric and ultrustructural evaluation.

BACKGROUND
Treatment of female pattern hair loss (FPHL) is frustrating for both patients and doctors. Mesotherapy is a novel treatment for hair fall and its efficacy in FPHL has not been evaluated.


OBJECTIVE
Evaluation of the efficacy and safety of mesotherapy using dutasteride-containing preparation in treatment of FPHL.


METHODS
This study included 126 female patients with FPHL. They were classified into two groups; group I (86 patients) injected with dutasteride-containing preparation and group II (40 control patients) injected with saline. Patients received 12 sessions and were evaluated at the 18th week by: photographic assessment, hair pull test, hair diameter and patient self-assessment. Ultrastructural evaluation was done for three patients.


RESULTS
After mesotherapy with dutasteride-containing preparation, photographic improvement occurred in 62.8% of patients compared with 17.5% in control group (P < 0.05), mean number of epilated hairs was significantly decreased (P < 0.05), mean hair diameter was significantly increased (P < 0.05). Patient self-assessment showed statistically significant improvement compared with the controls (P < 0.05). There was a negative correlation between degree of improvement and duration of FPHL (P < 0.05). Side effects were minimal with no statistically significant difference between the two groups (P > 0.05). Ultrastructural examination of pretreated hairs revealed absent cuticle in one patient and focal destruction of the cuticle in the second patient, which reappeared in both after therapy.


CONCLUSION
We concluded that mesotherapy with dutasteride-containing preparation was effective, tolerable and minimally invasive treatment modality in FPHL with better response for shorter duration of the disease.
Lung nodules: improved detection with software that suppresses the rib and clavicle on chest radiographs.

PURPOSE
To demonstrate possible superiority in the performance of a radiologist who is tasked with detecting actionable nodules and aided by the bone suppression and soft-tissue visualization algorithm of a new software program that produces a modified image by suppressing the ribs and clavicles, filtering noise, and equalizing the contrast in the area of the lungs.


MATERIALS AND METHODS
The study and use of anonymized and deidentified data received approval from the MedStar-Georgetown University Oncology Institutional Review Board. Informed consent was obtained from 15 study radiologists. The study radiologists participated as observers in a reader study of 368 patients in an approximately 2:1 cancer-free-to-cancer ratio. The localized receiver operating characteristic (LROC) method was used for analyses. Images were rerandomized for each radiologist. Each patient image was sequentially read, first with the standard radiograph and then with the software-aided image. Normal studies were confirmed with computed tomography (CT), follow-up, and/or panel consensus.


RESULTS
Each reader and the combined scores of the 15 readers showed improvement. The area under the combined LROC curve increased significantly from 0.460 unaided to 0.558 aided by visualization software (P = .0001). When measured according to the reader's indication that a case should be sent or not sent for CT or biopsy, sensitivity for cancer detection increased from 49.5% unaided to 66.3% aided by software (P < .0001); specificity decreased from 96.1% to 91.8% (P = .004). Seventy-four percent of the aided detections occurred in cancers with 70% or greater overlap of the bone and the nodule.


CONCLUSION
The radiologists using visualization software significantly increased their detection of lung cancers and benign nodules.
