Increasing Physical Activity in Women with Obesity to Promote Weight Loss

Obesity is a chronic disease associated with a multitude of lifelong chronic illnesses. Obesity impacts more than 42% of the United States population (CDC, 2021b). Physical inactivity is a major determinant of obesity (Muerer et al., 2019). The purpose of this evidence-based practice (EBP) project was to promote a greater reduction in body mass index (BMI) of the participants enrolled in an existing wellness program at the EBP practice site by increasing the physical activity level of the participants compared to standard protocol. The existing wellness program’s standard protocol included diet modifications, physical activity encouragement, and medication management. The EBP project aimed to increase physical activity using goal setting, self-monitoring, and continuous feedback. The sample included twenty participants newly enrolled in the existing wellness program in 2021 with a BMI greater than or equal to 25 kg/m2 . The participants were followed for a twelve-week period, and the BMI reduction of the group was compared to the BMI reduction of participants from the previous year who followed the standard protocol of the wellness program. Each participant’s BMI was calculated at the initial visit, at the six-week visit, and at the twelve-week visit. Data between the groups were analyzed using a paired t-test to compare the percent change in BMI at six and twelve weeks between both groups. It was found that the participants using standard protocol decreased BMI by 2.78%. Participants in the EBP project decreased BMI by 3.42%. However, the results were not found to be statistically significant. When comparing the ratio of attrition of both groups, 55% of participants in the comparison group failed to complete the program. In comparison, 30% of participants in the intervention group failed to complete the program. These findings indicated that although the EBP project did not result in a statistically significant decrease in BMI, the EBP project increased participant involvement in the program

A Contribution to the Biochemical Characterization of Allergens in Pollen Extracts of Secale Cereale

Buffe:r; extracts of pollen from Secale cereale as used ii+ therapy of pollinosis were prepa~edl. All the extracts were found active upon intradermal test in pollen sensitive subjects. Electro;phoretic and chromatographic analysis revealed that the extracts contain seven ninhydrin reacting components. Two amino acids, proline and [ysine, and five others (very probably polypeptides) were found to be components of the extract. Two major peptide components (C2 and D) were isolated and amino acids composition of acid hydrolyzates determined. Component C2 contained Asp., Glu., Ser., Gly., Thr., Lys., Tyr., (Cys.?), and D component Asp., Glu., Ser., (Cys.?), Gly., Thr., Tyr., V,al., Pro. I:n the original pollen extract\u27s hydrolyzate His., Phen., Leu., not certainly Tryp,, and Isoleu. were found in addition to the amino acids cited above. Of carbohydrates glucose, galactose and fructose were detected

Adherence to Nutrition and Physical Activity Cancer Prevention Guidelines and Development of Colorectal Adenoma.

Adherence to the American Cancer Society's (ACS) Nutrition and Physical Activity Cancer Prevention Guidelines is associated with reductions in overall cancer incidence and mortality, including site-specific cancers such as colorectal cancer. We examined the relationship between baseline adherence to the ACS guidelines and (1) baseline adenoma characteristics and (2) odds of recurrent colorectal adenomas over 3 years of follow-up. Cross-sectional and prospective analyses with a pooled sample of participants from the Wheat Bran Fiber (n = 503) and Ursodeoxycholic Acid (n = 854) trials were performed. A cumulative adherence score was constructed using baseline self-reported data regarding body size, diet, physical activity and alcohol consumption. Multivariable logistic regression demonstrated significantly reduced odds of having three or more adenomas at baseline for moderately adherent (odds ratio [OR] = 0.67, 95% confidence intervals [CI]: 0.46⁻0.99) and highly adherent (OR = 0.50, 95% CI: 0.31⁻0.81) participants compared to low adherers (p-trend = 0.005). Conversely, guideline adherence was not associated with development of recurrent colorectal adenoma (moderate adherence OR = 1.16, 95% CI: 0.85⁻1.59, high adherence OR = 1.23, 95% CI: 0.85⁻1.79)

Weyl formulas for annular ray-splitting billiards

We consider the distribution of eigenvalues for the wave equation in annular (electromagnetic or acoustic) ray-splitting billiards. These systems are interesting in that the derivation of the associated smoothed spectral counting function can be considered as a canonical problem. This is achieved by extending a formalism developed by Berry and Howls for ordinary (without ray-splitting) billiards. Our results are confirmed by numerical computations and permit us to infer a set of rules useful in order to obtain Weyl formulas for more general ray-splitting billiards

Supersymmetric Extensions of Calogero--Moser--Sutherland like Models: Construction and Some Solutions

We introduce a new class of models for interacting particles. Our construction is based on Jacobians for the radial coordinates on certain superspaces. The resulting models contain two parameters determining the strengths of the interactions. This extends and generalizes the models of the Calogero--Moser--Sutherland type for interacting particles in ordinary spaces. The latter ones are included in our models as special cases. Using results which we obtained previously for spherical functions in superspaces, we obtain various properties and some explicit forms for the solutions. We present physical interpretations. Our models involve two kinds of interacting particles. One of the models can be viewed as describing interacting electrons in a lower and upper band of a one--dimensional semiconductor. Another model is quasi--two--dimensional. Two kinds of particles are confined to two different spatial directions, the interaction contains dipole--dipole or tensor forces.Comment: 21 pages, 4 figure

La santé en Suisse : le point sur les maladies chroniques : rapport national sur la santé 2015

Le vieillissement de la population va de pair avec une progression constante des maladies chroniques dans notre société. Les modes de vie modernes favorisent l'apparition de ces maladies, notamment par le tabagisme, par le manque d'activité physique et par une alimentation déséquilibrée. Les maladies chroniques somatiques sont aujourd'hui dans la ligne de mire des responsables de la politique de la santé. Elles constituent, avec les maladies chroniques psychiques, dont les conséquences sont multiples, un défi de taille pour notre système de santé et un problème majeur de santé publique. La prise en charge des maladies chroniques requiert une bonne coordination du système de santé. La Confédération et les cantons y travaillent activement en s'engageant par exemple dans le domaine du personnel de santé et de l'organisation des structures de soins. Confédération et cantons contribuent à faire en sorte que les maladies chroniques psychiques ou somatiques deviennent moins fréquentes ou soient traitées suffisamment tôt. Tels sont les objectifs des politiques de promotion de la santé et de prévention des maladies, dont l'importance ira croissant à l'avenir. Le présent rapport national sur la santé donne une vue d'ensemble de la santé dans la population suisse; il met en lumière certains aspects importants des maladies chroniques dans notre pays. Puisse-t-il donner des impulsions nouvelles et aider les acteurs du système suisse de santé à maîtriser ensemble les défis liés à ces maladies

Survival Probability of a Doorway State in regular and chaotic environments

We calculate survival probability of a special state which couples randomly to a regular or chaotic environment. The environment is modelled by a suitably chosen random matrix ensemble. The exact results exhibit non--perturbative features as revival of probability and non--ergodicity. The role of background complexity and of coupling complexity is discussed as well.Comment: 19 pages 5 Figure

Swimming in ice cold water

Introduction: We investigated two athletes swimming in 4°C for 23min (1.3km, swimmer 1) and 42min (2.2km, swimmer 2), respectively. Materials and methods: Pre swim, percent body fat was determined; post swim, core temperature was measured. Results: The core temperature of swimmer 2 was: 37.0°C immediately before the start, 32°C 20min after getting out of the water, and 35.5°C 80min after finishing the swim. Conclusion: We assume that the higher skin-fold thickness and body fat of swimmer 2 enabled him to perform longer. In addition to this, mental power and experience in cold water swimming must be considered. In any athlete aiming at swimming in water of less than 5°C, body core temperature and heart rate should be continuously monitored in order to detect a body core temperature below 32°C and arrhythmia to pull the athlete out of the water before life-threatening circumstances occu
