Background: This study investigated the psychometric properties of the 9-Item Shared Decision-Making Questionnaire (SDM-Q-9) and the 9-Item Shared Decision-Making Questionnaire–Physician version (SDM-Q-Doc) using comprehensive and thorough psychometric methods in an oncology setting. Methods: Cancer survivors (n=1783; 928 [52.05%] males) and physicians (n=154; 121[78.58%] males) participated in this study. Each cancer survivor completed the SDM-Q-9. Physicians completed the SDM-Q-Doc for each of their cancer patient. Confirmatory factor analysis (CFA) and Rasch model were used to test the psychometric properties of SDM-Q-9 and SDM-Q-Doc. Results: SDM-Q-9 and SDM-Q-Doc demonstrated unidimensional structure in CFA and Rasch model. In addition, the measurement invariance was supported for both SDM-Q-9 and SDM-QDoc across sex using the multigroup CFA. Rash analysis indicates no differential item functioning(DIF)across sex for all the SDM-Q-9 and SDM-Q-Doc items. SDM-Q-9 and SDM-Q-Doc were moderately correlated (r=0.41; P<0.001). Conclusion: SDM-Q-9 and SDM-Q-Doc are valid instruments to assess shared decision making in the oncology setting.

Background: Previous experimental work demonstrates that acute exercise may enhance episodic memory performance. However, limited research has examined the extent to which acute exercise influences false episodic memory production, and no studies, to date, have examined whether there is an intensity-specific effect of acute exercise on both true episodic and false episodic memories. Thus, the present experiment evaluated the effects of intensity-specific acute exercise on episodic memory and false episodic memory.Methods: A three-arm, parallel, between-group randomized controlled trial was employed in the University setting, with participants (N=60; Mage= 20.8 years) randomized into a moderate intensity exercise group (15-minute bout of treadmill exercise at 50% heart rate reserve), a high intensity exercise group (15-minute bout of treadmill exercise at 80% heart rate reserve), or a control group (time-matched period of sitting). True episodic and false episodic memory were both assessed using 6 word-lists from the Deese-Roediger-McDermott (DRM) paradigm, including both a short-term recall and a delayed memory recognition assessment. Results: For the number of words recalled across each of the 6 lists, there was a significant main effect for list (P<0.001, η2p=0.15), marginally significant main effect for group (P=0.07, η2p=0.09), but no list by group interaction effect (P=0.44, η2p=0.03). Those in the high-intensity exercise group recalled significantly (P<0.05) more words than the control group. For the false episodic word recall, across various lists, high-intensity acute exercise was associated with a greater rate of false episodic memories. For the memory recognition task, there was no main effect for word type (P=0.46, η2p=0.01), group (P=0.4443, η2p=.03), word type by group interaction (P=0.44,η2p=0.03), recall by group interaction (P=0.4441, η2p=0.04), or word type by recall by group interaction (P=0.32, η2p=0.04). However, there was a main effect for recall (P<0.001, η2p=.54)and a word type by recall interaction (P<0.001, η2p=0.77).Conclusion: These findings suggest that acute high-intensity exercise may enhance true episodic memories, and, possibly, also increase the rate of false episodic memories. We discuss these findings in the context of how different acute exercise intensities may have unique and differential effects on underlying mechanistic processes related to true and false episodic memory.

Background: The United States Department of Health and Human Services (USDHHS)recommends that adults achieve 150 minutes per week of moderate-intensity aerobic activity.Most African American women do not meet these guidelines. The purpose of this study was to determine the efficacy of an intervention based on the fourth generation, multi-theory model (MTM) of health behavior change for initiating and sustaining physical activity among African American women when compared to a first generation, knowledge-based intervention. Methods: The randomized controlled trial (RCT) utilized a pre-test, post-test and 6-week followup evaluation with an experimental (n=25) group and a comparison group (n=23). Process evaluation for satisfaction and program fidelity was conducted along with impact evaluation for changes in MTM constructs, intent to initiate and sustain physical activity, minutes of physical activity, body mass index (BMI), waist circumference and blood pressure in hypertensives. Results:The MTM-based intervention proved significantly efficacious in increasing the minutes of physical activity from pre-test mean of 37 minutes to 172 minutes at follow-up (mean difference135.08 minutes, 95% CI: 106.04 to 164.13, P<0.0001), reducing waist circumference from pretest mean of 39 inches to 38 inches at follow-up (mean difference -1.12 inches, 95% CI: -1.70 to-0.545, P<0.001) and modifying the MTM construct of changes in physical environment from a mean of 7 units at pre-test to 9 units at follow-up (mean difference 2.08 units, 95% CI: 0.73 to 3.43, P<0.004) when compared to the knowledge-based intervention over time. Conclusion: There were directional improvements in the mean scores for most of the study variables over time for the MTM intervention group and statistically significant improvement in minutes of physical activity and waist circumference.

Background: Adequate iodine intake by women in child-bearing age affects fetus neurodevelopment during pregnancy. A majority of previous studies has investigated iodine status among children, and there is limited data on female adolescents who are more exposed to consequences of iodine deficiency (ID) in their near-future pregnancies; thus, we aimed to assess iodine status, and knowledge on iodine deficiency disorders (IDDs) among adolescent school girls (14-19 years old) in Shahriar, Iran. Methods: This cross-sectional study was conducted among 223 female students selected through multi-stage cluster sampling from 12 schools. Iodine and creatinine concentrations were measured in casual urine samples. Iodine content of household salts was also assessed.Data on intake of salt and iodine-rich food sources were collected applying a food frequency questionnaire (FFQ), and knowledge about iodine and IDDs were assessed by a questionnaire. Results: Median and Mean (95% CI) concentrations of urinary iodine and creatinine were 129 µg/L, 137.62 µg/L (95% CI: 126.28, 148.95) and 1.72 g/L, 1.86 g/L (95% CI: 0.55-3.17),respectively. The frequency of mild, moderate and severe ID were 22.4%, 14.3% and 0%,respectively; 43.5% had adequate, and 3.1% had excessive urinary iodine levels. Mean saltiodine concentration was 21.69 (SD=10.56) ppm. Mean knowledge score was 12.7 (SD=3.44).About half of the students had a poor (25.1%) or fair (24.2%) knowledge about iodine deficiency.Adjusting for the confounders, no significant positive association was found between knowledge about iodine-rich food sources and goitrogens with urinary iodine excretion.Conclusion: Adolescent girls in Shahriar had relatively poor knowledge of iodine, and about one third of them suffered from ID.

Background: Physical activity levels were low for pregnant and postpartum participants in a diet and physical activity intervention. To explore micro level characteristics of participants’neighborhoods related to physical activity, an ancillary study was conducted. Methods: This cross-sectional study encompassed the neighborhood street segments of women participating in a diet and physical activity intervention that was conducted in the Lower Mississippi Delta. A neighborhood was defined as all street segments within one-fourth walking mile of a participant’s home address. Street segments were measured using the Rural Active Living Assessment’s Street Segment Assessment tool. In the field and on foot, raters measured street segments using neighborhood maps with segments identified. Results: Mean street segment length was 0.22 miles (SD = 0.14). All segments had flat terrain with residential (98%), open spaces (74%), and public/civic (34%) as the most prevalent land uses. Almost three-fourths of segments did not have any sidewalks (69%), sidewalk buffers or defined shoulders (73%), crosswalks or pedestrian signage (69%), or posted speed limits (74%).However, 88% had stop signs and almost all (96%) had street lighting and were paved multi lane roads (95%) with low traffic volume (90%). Most residential structures present were single family detached homes (95%) and the most common public/civic and commercial structures were churches (24%) and convenience stores (9%), respectively. Almost all of the street segments were rated as walk able (99%) and aesthetically pleasing (94%). Conclusion: Neighborhood street segments surrounding Delta Healthy Sprouts participants’homes were walk able and aesthetically pleasing. However, safety features such as sidewalks,pedestrian signage, and posted speed limit signs were lacking. To address these inadequate pedestrian safety features, infrastructure changes are needed for small rural towns.

Background: The purpose of this review was to evaluate whether acute exercise intensities have unique effects on memory function, and whether this is influenced by memory type as well as the temporality of the acute exercise bout.Methods: A systematic review was employed, using several databases (PubMed, PsychInfo,Sports Discus, Google Scholar, Embase).Results: In total, 9 articles met the study criteria. All 9 studies evaluated either working memory capacity or episodic-related memory function. The main findings across these studies were 1) when acute exercise occurs before the memory task, high-intensity exercise may be less favorable for working memory but may favor episodic memory; 2) when acute exercise occurs during the memory task, high-intensity exercise may be less favorable for working memory capacity; and 3) high-intensity exercise may not associate with long-term memory function when it occurs shortly after memory encoding.Conclusion: The relationship between acute exercise and memory is complex and may vary based on the intensity of exercise, the temporality of exercise, and the memory type evaluated.

Background: The cognitive function could be affected following exposure to organic solvents.The purpose of this study was to examine the cognitive performance of workers exposed to different levels of organic solvents in a painting unit of an automotive industry.Methods: This case-control study was conducted, in 2017, on 121 and 111 workers from the painting and assembly units of an automotive industry as the case and control groups,respectively. Exposure of workers to organic solvents were determined according to National Institute for Occupational Safety and Health (NIOSH) method. The cognitive performance of the studied population was evaluated by the computerized tests.Results: The obtained scores of the N-Back in 1 and 2 blocks and the simple reaction time tests(SRTTs) were significantly differed in the exposed group (p<0.05). No significant difference was observed between case and control groups in the Stroop test score (p> 0.05). Moreover, a significant relationship between the hazard quotient and the cognitive function test scores were observed except the Stroop test.Conclusion: Exposure to organic solvents affect the cognitive functions even below the Occupational Exposure Limits (OELs). Moreover, workers with high exposure levels of organic solvents had highest risk of poor memory and reaction time.

Background: The present study aimed at assessing the validity of self-reported drug use in people aged 35 and older in a pilot phase of a population-based cohort study.Methods: A total of 1038 adults over 35 years old in Khamene city in East Azerbaijan province were recruited for the pilot phase of Azar cohort; a province-level of a nationwide PERSIAN cohort study completing a questionnaire and providing biological samples from October to December 2014. Information about the history and duration of smoking tobacco, using drug and medication were obtained by the physician. The validity of the drug use was assessed through comparing the questionnaire response with three urine strip tests for the detection of morphine, amphetamine and methamphetamine among 259 randomly selected subjects.Results: The prevalence of drug use according to self-report was 2.6% (95% CI: 1.7%-3.8%).One-step drug test as the gold standard for the use of drug self-reported demonstrated a sensitivity(95% CI) and specificity 15% (10-22) and 99.7% (98.9%-99.9%) respectively. All participants with positive self-report were male; however, in the urine analysis drug test, it was positive for 7out of 68 randomly selected women.Conclusion: The validity of self-reported drug use in this population was low; therefore, the self reported use of the drug should be used with caution in this population. It is recommended to use alternative techniques to improve the validity of data using the self-report procedure.

Background: The purpose was to determine if an 8-week nutrition education and exercise program for families could influence health and fitness parameters, and retention of nutrition knowledge. Methods: Eighteen children (mean age: 10.52 ± 1.26 year; 50% boys, 50% girls; 56% white, 25% black, 19% multiracial) participated in the Families in Transformation (FIT) program. Preand post-study anthropocentric, blood pressure, fitness, and nutrition knowledge data was collected. Results: Diastolic blood pressure decreased for the total group (66.63 ± 8.81 to 63.75 ± 11.81mm Hg). Significant (P < 0.05) increases were seen for the group for push-ups (14.31 ± 7.62 to 19.63 ± 6.62) and chair squats (30.50 ± 10.21 to 34.44 ± 7.39). The reinforcing physical activity group performed significantly better on nutrition knowledge quizzes. Conclusion: Although, body mass index (BMI) z-scores did not change, there was a decrease in diastolic blood pressure, increase in fitness parameters, and increased retention of nutrition knowledge.

Background: This study explored the French media’s presentation of ideas and medical information about prostate cancer (PC) that may influence men’s understanding, attitudes and behavior. Methods: A qualitative media content analysis centered on PC information delivered by French professional media. The selected data were produced in the aftermath of the High Health Authority's decision in 2008 not to recommend systematic screening by prostate specific antigen(PSA) for men over 50. Source was the Media Archives of the French National Library. Content was analyzed from 15 television programs, 14 radio programs, and 55 articles from 35 popular French newspapers (online and printed, weekly and monthly) and 20 magazines. Audio content was narrated into textual form and submitted to manual coding along with the print content.Results: Television and radio content focused on the nature of PC, screening and treatment,and conveyed a gender-centric position linked to male sexuality and virility. Newspapers and magazines targeted the testing controversy, the lack of consensus among professionals, and scientific advances in screening and treatment.Conclusion: Media participation in the European testing debate is valuable for allowing patients to hear all opinions on PC risk factors. Debate on testing policy contributes to confusion and uncertainty regarding appropriate action.
