Journal of Physical Activity and Health

Background: Innovative methods are warranted to optimize prenatal outcomes. This study's objective was to determine if a web-based behavioral intervention (BI) can prevent excessive gestational weight gain (GWG) by increasing physical activity (PA). Methods: Participants were randomized to usual care (UC; n = 21) or BI (n = 24) between 10 to 14 weeks gestation. GWG, PA, and diet were assessed at baseline, mid-, and late pregnancy. Results: No differences in GWG or adherence to GWG recommendations presented between groups. Total UC MET-minutes significantly decreased from baseline to late-pregnancy (1,234 ± 372 MET-minutes, P = .013). Mid-pregnancy sustained PA was greater for BI than UC (20-minute PA bouts: 122 ± 106 vs. 46 ± 48 minutes/week, P = .005; 30-minute PA bouts: 74 ± 70 vs. 14 ± 24 minutes/week, P < .001), and greater for BI at mid-pregnancy compared with baseline (20-minute PA bouts: 61.3 ± 21.9; 30-minute PA bouts: 39.6 ± 14.8, both P < .05). BI energy intake at mid-pregnancy significantly increased from baseline (336 ± 127 kcals, P = .04) and was significantly greater than UC (2,503 ± 703 vs. 1,894 ± 594, P = .005). Conclusions: Sedentary pregnant women should increase PA but may need additional dietary counseling to prevent excessive GWG. © 2016 Human Kinetics, Inc. Source

Anxiety, Stress and Coping

Background: High rates of stress-related problems in college students and low utilization of treatment options demonstrate the need for effective stress-reducing interventions that can be self-regulated. This study compared the effect of brief paced-breathing with biofeedback and exercise interventions on heart rate variability, state anxiety and affect. Methods: Students (n = 32) with high levels of perceived stress completed three 10-min interventions on separate days: paced-breathing with biofeedback (Biofeedback), a self-paced walk (Exercise), and an attention control condition of quiet studying (Quiet Study). Anxiety and affect were measured before (Pre), immediately after (Post0) and 15 mins after (Post15) the intervention. Heart rate variability was measured pre- and post-intervention using electrocardiogram. Results: Biofeedback reduced anxiety more than the exercise condition (Pre to Post0: Biofeedback d = −0.48, Exercise d = −0.13). Secondly, Exercise temporarily increased energy (Pre to Post0: d = 0.67), whereas Biofeedback temporarily increased calmness (Pre to Post0: d = 0.51). All conditions significantly increased total heart rate variability (p <.05). Conclusions: Biofeedback and Exercise interventions improved emotional states in high-stress college students, but the type of change observed (i.e. energizing, calming or anxiety reducing) depended upon the condition. © 2015 Taylor & Francis.

"⋯ do not take from me your laughter.. it opens for me all the doors of life" - Pablo NerudaBefore they speak or walk or crawl, infants joke. Infant laughter captured the attention of Aristotle, who thought it was the sign of the entry of the soul into the body, and of Darwin, who noted its emergence in the fourth month of life. Darwin saw such laughter as the early appreciation of humour, the presence at this age of which should not surprise us too much, given the early emergence of play in other mammals. In the twentieth century, however, these observations faded from scientific attention; humour began to be seen as an intellectual achievement requiring complex cognitive abilities, with infant laughter seen merely as a reaction to external stimuli. Recent research, however, has uncovered remarkable cognitive and emotional sensitivities in very young infants. And, as it turns out, humour and laughter in infants offer a rich source of insights into their understanding of the world, and indeed for our understanding of infants. The study of infant humour is no joke. © 2015 Elsevier Ltd. All rights reserved. Source

Applied Geochemistry

Detailed studies were conducted at Big Boiler hot spring in Lassen Volcanic National Park, CA, and Ojo Caliente hot spring in Yellowstone National Park, WY, to measure the flow rate and characterize the flow regime of hot spring drainages. These drainages represent some of the most dynamic interfaces between the hydrosphere and atmosphere with steep temperature gradients and chemical gradients. The rate of thermal disequilibrium and chemical disequilibrium dissipation depends on the flow rate and flow regime.The drainage of each hot spring was divided into ten or more segments and water samples were collected at segment boundaries. Fluid flow velocity throughout the drainage was measured using an in situ flow probe where possible and by determining the advancement of a red food dye tracer through the flow channel. A combination of field and laboratory studies was used to adapt a method based on the transport-controlled dissolution rate of gypsum to characterize the flow regime throughout the drainages. Laboratory experiments as a well as a deployment in an artificial drainage were conducted to validate the application of this method for hot spring environments. The deployment of the gypsum tablets was complemented by using digital videography to record the nature of the flow regime throughout the drainages. In situ flow probe measurements were not possible at all locations. The data obtained with the probe showed a range of values that was in reasonable agreement with the flow rates obtained using the dye tracer. The average flow rate based on advancement of dye tracer determined at Big Boiler was 0.22. m/s in both 2000 and 2001, while in Ojo Caliente flow rate varied from 0.39. m/s in 2001 to 0.45. m/s in 2002. The results of the gypsum dissolution measurement in the field yield boundary layer thicknesses between 8 and 38. μm, with most values between 15 and 25. μm, indicating well-developed turbulent flow throughout the drainages. The results, consistent with videography, indicate that gypsum dissolution rates based on the deployment of well-characterized and pure gypsum tablets can be used in hot-spring environments. An analysis of cooling rates within the drainages illustrates the importance of turbulent flow in cooling the waters. © 2015 Elsevier Ltd. Source

Imatinib mesylate has been associated with the changes in bone turnover. We report a case of the development of tissue calcification in a patient on long-term therapy with this drug. A 48-year-old male patient with gastrointestinal stromal tumor and liver metastasis complained of abdominal pain. His treatment included hepatic artery chemoembolization and partial hepatectomy in addition to chronic imatinib mesylate for 4 years. On physical examination, he had a peritoneal mass just beneath the laparotomy incision scar that, after resection, was found to be dystrophic bone formation. Based on the previous studies suggesting bone changes due to chronic therapy with imatinib mesylate, we believe that the patient's new bone formation was causally related to the use of this drug. To our knowledge, there are no similar reported cases in the literature. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav. Source
