Literature ReviewEvaluation (Cryptorchidism and Maternal Alcohol Essay

Literature ReviewEvaluation (Cryptorchidism and Maternal Alcohol Consumption during Pregnancy) - Essay Example Before doing the purpose statement, the authors have briefly discussed the problem of cryptorchidism in that it is a very common genital malformation in males, of which the aetiology is unknown. A brief review of literature on this topic has been done by the authors, and they have clearly indicated the possibility of implications of developmental genetic defects and other fetomaternal factors. Out of this literature review, the authors make a case for such a study in that the prevalence of such a disorder has been connected with parental lifestyle changes and environmental factors. Since normal testicular descent happens in two phases, transabdominal from 8 to 17 gestational weeks and inguinoscrotal from 26 to 35 weeks of gestation. Therefore, the authors argue that the physical, chemical, and biological, and endocrinologic stimuli for descent of testes lie in the fetus and the mother. The literature review assumes great importance here, since to hypothesize the research question, th e authors have done a thorough search of relevant literature. The authors connect maternal alcohol consumption as a probably cause for this. ... The authors rightly argue that most of the existing researches used retrospective data that might be compromised by recall and selection bias. Therefore, the authors establish the purpose of the research in that if a positive association is probable and indeed exists, it would be worthwhile to undertake the research so it may help prevent this problem in the newborn. Hypothesis: With a precise and succinct literature review, the authors logically derive the scientific thread of the assumption that maternal alcohol consumption may corrupt the fetal environment in uterus during pregnancy when the fetus is developing. Therefore, the reader is keen to believe the hypothesis that maternal alcohol consumption during pregnancy is positively associated with cryptorchidism. However, the gap in the existing research can be filled up by a prospective population-based cohort of pregnant women and their male offspring. To be able to do this, the authors used both qualitative and quantitative information on maternal alcohol consumption and other data on confounding lifestyle factors. The hypothesis statement is precise, well-structured, and generates interest in the reader, so he is keen to know the findings in the authors' research. Methods: Since this is a questionnaire study across different locations, the authors standardised the questionnaire, and the responses were collected in the beginning of the third trimester of pregnancy. Detailed history of alcoholism was collected in relationship with the frequency, amount, and binge episodes. Other lifestyle parameters were also collected. It was a joint perspective birth cohort study with sufficient sampling to be able to generate validity and reliability. Simultaneous with the

Investigation of REDBULL - Research Paper Example caffeine and glucose on the cognitive and cardiovascular performances of students during a two hour long lecture. An interventional study was conducted to test whether stimulation (caffeine, caffeine + glucose, glucose drink) can effect physiological and cognitive changes in an individual within a controlled environment amongst 16 students. The participants were required to fill out a lifestyle questionnaire after which their cardiovascular parameters (i.e. heart rate and MAP) and cognitive performance (via a reaction time test) were assessed. Subsequently, they were asked to consume a 250 ml drink on 7 different occasions, from a selection of the following beverages: water, red bull, red bull with no added sugar and soft drink. The participants were then asked to wear an ambulatory device during a 2 hour lecture which was set to read their heart rate and blood pressure every 30 min. At the end of the 2 hour lecture, the participants were required to undertake a repeat reaction time test. ... Thus, it can be concluded that the consumption of Energy Drinks results in an improvement in cardiovascular and cognitive performance and both the glucose and the caffeine component have a contributory role in the improvement of these parameters. Introduction: Over the last few decades, there has been a witnessed increase in popularity of diet/health food and other food fads, and a concurrent rise in the popularity and demand for functional foods, an example of which are energy drinks, such as Red Bull (Smit et al., 2004; Finnegan, 2003). Energy Drinks are categorized as â€Å"stimulant drinks,† which have been defined by the Stimulant Drinks Committee as ‘a beverage which typically contains caffeine, taurine and vitamin(s) and may contain an energy source (e.g. carbohydrate) and/or other substance(s), marketed for the specific purpose of providing real or perceived enhanced physiological and/or performance effects (Stimulant Drinks Committee, 2003, p. iv).’ The m anufacturers of Energy Drinks claim that such drinks enhance both mental and physical functions, resulting in improved physical endurance, increased alertness and concentration, augmented reaction speed and an elevated mood (Kim, 2003; Kaminer, 2010). â€Å"Energy Drinks† are so called because they are thought to be stimulant in nature, providing the consumers with an instant boost of energy and alertness and decreasing lethargy and sleepiness, have been present in the global market in their current guise from the late nineties, but under the banner stimulant drinks, these have been sold and marketed for many years, and have been gaining widespread fame ever since (Kim, 2003). For example, Lucozade, a UK branded energy
