An exploratory study on perceived relationship of alcohol, caffeine, and physical activity on hot flashes in menopausal women  [PDF]
Jay Kandiah, Valerie Amend
Health (Health) , 2010, DOI: 10.4236/health.2010.29146
Abstract: This study examined the effects of caffeine, alcohol, and physical activity (PA) on the perceived frequency and severity of hot flashes in menopausal women. Female employees at a Mid-Western university were invited to participate in an on-line survey. The 26-itemized Wo- men’s Health Survey (WHS) included questions regarding demographics, menopausal stage, experience of hot flashes, consumption of caffeinated beverages and alcohol, and participation in PA. One-hundred and ninety-six women completed the study. Ordinary Least Squares regressions revealed PA, caffeine, and alcohol intake were significant in predicting the severity of hot flashes (R2 = 0.068, F(6,180) = 2.195, p = 0.046), though they did not predict frequency of hot flashes (R2 = 0.043, F(6,184) = 1.39, p = 0.221). Participation in aerobic PA increased frequency of hot flashes (p = 0.031); while higher intensity of aerobic PA had an inverse relationship on both frequency and severity of hot flashes (p = 0.011, p = 0.003, respectively). Spearman correlations demonstrated a positive relationship between caffeinated soda intake and frequency (r = 0.17, p = 0.06) and severity (r = 0.19, p = 0.04) of hot flashes. Beverage consumption and PA may predict severity of hot flashes in women. Less frequent, higher intensity aerobic PA may lead to fewer, less severe hot flashes.
Teaching New Mothers about Infant Feeding Cues May Increase Breastfeeding Duration  [PDF]
Jay Kandiah, Charlene Burian, Valerie Amend
Food and Nutrition Sciences (FNS) , 2011, DOI: 10.4236/fns.2011.24037
Abstract: The objective of this pilot study was to compare two different methods of educating prenatal women regarding breast-feeding. Comparisons were made between traditional and innovative methods to determine which was more effective in increasing breastfeeding duration. Over a 32 month period, 197 prenatal women were assigned to either a control (C, n = 139) or an experimental (E, n = 51) group. The C group received standard breastfeeding education, while the E group received standard education in addition to information about infant hunger cues. Cox Regression and Kap-lan- Meier analysis were performed. Estimated mean number of weeks for C and E groups to continue breastfeeding was 14.3 + 17.4 weeks and 18.5 + 17.1 weeks, respectively. At 26 weeks, duration of breastfeeding approached significance (chi square = 2.907, df = 1, p = 0.088), indicating probability of continuing to breastfeed was about 28% better for those in E group when compared to C group. Duration of breastfeeding may increase when prenatal women are taught to identify infant behavior such as hunger cues.
Compliance of a Small Convenience Sample and Efficacy of Short Term Modified Carbohydrate Diet on Weight Loss in Overweight College Students: A Pilot Study  [PDF]
Jay Kandiah, Dawn Brinson, Valerie Amend
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.35095
Abstract: The purpose of this pilot study was to determine overweight students’ compliance on low and moderate carbohydrate diets and its influence on weight loss. The 28 day study was divided into two experimental periods of 14 days each. For the first 14 days, Group 1 (n = 6) received LC diet (30 grams carbohydrate/day with ad libitum intake of protein and fat), and group 2 (n = 8) received MC diet (60 grams carbohydrate/day with ad libitum intake of protein and fat). After 14 days, there was a crossover of the diets. Two random 24-hour diet records, urinary ketones, and daily emotional and physical well-being journals evaluated participants’ dietary compliance. Height, weight, body mass index, and urine ketones were assessed at baseline, days 14 and 28. A 2 × 2 ANOVA was conducted to examine the difference between groups and to determine if a difference existed from baseline to the end of the diet period. During the study period, ir- respective of carbohydrate levels, a vast majority of participants had above or below the recommended intake of carbo- hydrates, indicating non-compliance due to various reasons. During each experimental period, although weight loss differences between groups over time did not exist, there was a significant weight loss within subjects over time (p < 0.01). Presence of urinary ketones during the dietary interventions were not statistically significant. In conclusion, mod-ified carbohydrate diets were effective with weight loss; however participants were non-compliant with their de- fined dietary protocols.

Supersolvable restrictions of reflection arrangements
N. Amend,T. Hoge,G. Roehrle
Mathematics , 2013,
Abstract: Let A = (A,V) be a complex hyperplane arrangement and let L(A) denote its intersection lattice. The arrangement A is called supersolvable, provided its lattice L(A) is supersolvable. For X in L(A), it is known that the restriction A^X is supersolvable provided A is. Suppose that W is a finite, unitary reflection group acting on the complex vector space V. Let A(W) = (A(W), V) be its associated hyperplane arrangement. In earlier work by the last two authors, we classified all supersolvable reflection arrangements. Extending this work, the aim of this note is to determine all supersolvable restrictions of reflection arrangements. It turns out that apart from the obvious restrictions of supersolvable reflection arrangements there are only a few additional instances. Moreover, in our previous work, we classified all inductively free restrictions A(W)^X of reflection arrangements A(W). Since every supersolvable arrangement is inductively free, the supersolvable restrictions A(W)^X of reflection arrangements A(W) form a natural subclass of the class of inductively free restrictions A(W)^X. Finally, we characterize the irreducible supersolvable restrictions of reflection arrangements by the presence of modular elements of dimension 1 in their intersection lattice. This in turn shows that reflection arrangements as well as their restrictions are of fiber type if and only if they are strictly linearly fibered.

International Public Opinion on China’s Climate Change Policies  [PDF]

Abstract: With the emergence of a global public sphere and the revolution of global media, international public opinion has gained an intrinsic importance for effective multilateral cooperation. Global governance initiatives are subject to international public opinion, and climate change is the single most important global governance issue of our time. Tackling climate change requires a fundamental transformation of the global economy, with an emphasis on sustainable development. Due to its political and economic weight, China can push forward UN climate change negotiations, and can do so without compromising its national development goals (China’s National Climate Change Programme, 2007). China’s national policies are beyond what is required from developing nations, but international public opinion often perceives a different message. This paper holds that a national branding strategy will help convey China’s current efforts, allowing a better understanding among nations in order to break the climate change negotiations deadlock. This research merged perception analysis and public opinion surveys with mass media qualitative and quantitative analysis to gain a full insight into what the international climate change decision-makers, opinion-leaders and general public think about China’s position at the UNFCCC negotiations. As seen in the findings of the present research, the climate of opinion is unfavorable to China. Overall, the results show that China is perceived as a negative influence in the negotiations. China’s climate change efforts are being overlooked by international public opinion. But the reason lies in China’s current discourse, where climate change and the environment are always downplayed by the right to develop (D’Hooghe, 2011). According to China’s 12th Five Year Plan, the new path for the country is marked by its commitment to achieve growth through low carbon development, with a strong focus on addressing climate change and energy challenges (Shealy & Dorian, 2007). The results of this study show that the positive intentions and actions of the Chinese government aren’t being accurately perceived by public opinion. The empirical findings in this study provide a new understanding of one specific part of the overall image that the world has about China. Whilst this study did not confirm unequivocally that international public opinion directly determines the outcomes of international negotiations and foreign policy, it did partially substantiate the concept that there’s a correlation between China’s public declarations and actions, the
Rekonstruktive Urologie des oberen und unteren Harntraktes - ein Therapieupdate

Journal für Urologie und Urogyn?kologie , 2009,
Abstract: Trotz des Fortschritts konservativer Therapiem glichkeiten ist für viele urologische Erkrankungen ein chirurgisches Vorgehen unabdingbar. Hieraus resultiert die Notwendigkeit einer ausgefeilten rekonstruktiven Chirurgie, um verloren gegangene Funktionen der einzelnen Urogenitalorgane zu ersetzen bzw. wiederherzustellen. In erster Linie bedingen ausgedehnte radikalchirurgische Eingriffe der Onkologischen Urologie einen rekonstruktiven Ersatz im Bereich des oberen und unteren Harntraktes. Neben der Rekonstruktiven Urologie als Teil der Onkologie werden diese Techniken auch für Krankheitsbilder au erhalb des onkologischen Krankheitskreises ben tigt. Der vorliegende Artikel gibt anhand Peer-reviewter Literatur einen überblick der therapeutischen M glichkeiten des Harnblasen- und Harnleiterersatzes, der rekonstruktiven Harnr hrenchirurgie und der M glichkeiten der operativen Korrektur der Nierenbeckenabgangsstenose. hnlich wie in anderen Fachrichtungen wird auch in der Urologie der Gewebeersatz durch Tissue Engineering im Labor und Tiermodell vorangetrieben. Es ist davon auszugehen, dass eine optimalere und damit funktionellere Rekonstruktion m glich und dadurch die Lebensqualit t der Patienten weitreichend verbessert wird. Durch Tissue Engineering wird ein Organ- und Gewebeersatz unter m glichst quivalenten anatomischen und funktionellen Gesichtspunkten m glich. Die Kombination altbew hrter Techniken mit innovativen Neuerungen wird sich vor allem in der nahen Zukunft an Therapieerfolg, Lebensqualit t und Patientenzufriedenheit messen müssen.
Aktuelle Therapiem glichkeiten des Benignen Prostata-Syndroms
Sievert KD,Kruck S,Amend B,Nagele U
Journal für Urologie und Urogyn?kologie , 2009,
Abstract: Das Benigne Prostata-Syndrom (BPS) des alternden Mannes stellt als nicht maligne Ver nderung der Prostata den h ufigsten Ausl ser einer irritativen und obstruktiven Miktionssymptomatik dar. Zur Therapie der BPS stehen wirkungsvolle medikament se, sowie bei weiterem Progress verschiedene operative Optionen zur Verfügung. In der Prim rtherapie versprechen Alpha-Blocker eine schnelle Symptomlinderung, jedoch stellen 5-Alpha-Reduktaseinhibitoren die einzige medikament se Therapieoption dar, die den zugrunde liegenden Krankheitsprozess hinausz gert und einen dauerhaften Therapieerfolg sichert. Aktuelle Studienergebnisse belegen eine deutliche Verringerung des Progressionsrisikos unter Anwendung beider Substanzen. Verschiedene innovative Operationsverfahren konkurrieren derzeit mit der klassischen transurethralen Prostataresektion (TUR-P) und weisen potentiell ein günstigeres Risikoprofil im Vergleich zur TUR-P, sowie eine deutliche Verringerung der Krankenhausaufenthaltsdauer und -kosten auf. Nachfolgend werden die aktuellen Therapieoptionen im Hinblick auf die derzeitige Studienlage beleuchtet.
