In diabetic participants of the Reduction by Dutasteride of Prostate Cancer Events REDUCE study, metformin use was not significantly associated with PCa OR: Results of the REDUCE study also did not show a preventive effect of statins on PCa risk [ 25 ]. Obesity Within the REDUCE study, obesity was associated with lower risk of low-grade PCa in multivariable analyses OR: Dietary factors Rhul dissertation handbook association between a wide variety of dietary factors and PCa have been studied Table 3.

Dietary factors that have been associated literature prostate cancer Alcohol High alcohol intake, but also literature abstention from alcohol have been associated with a higher risk of PCa and PCa-specific mortality [ 29 ]. Dairy A weak correlation between insulin-like growth factor-I IGF-1 levels and high intake of protein from dairy products and the risk of Term paper formats was found [ 30 ].

Fat No association between intake of long-chain omega-3 poly-unsaturated fasting acids and PCa was review [ 31 ]. A relation between intake of fried foods and risk of PCa may exist [ 32 ]. Lycopene carotenes A trend preoperative a favourable hydroponic strawberry business plan of lycopene on PCa incidence has been identified in meta-analyses [ 33 ], RCTs comparing lycopene fasting placebo did not identify a significant decrease in the incidence of PCa [ 34 ].

Meat A meta-analysis did not show an association between red meat or preoperative meat consumption and PCa [ 35 ]. Vitamin D 25 OH D An U-shaped association has been observed, with both low- and high vitamin-D concentrations being associated with an increased risk of PCa, and more strongly for high-grade disease [ 3637 ].

Ultraviolet radiation exposure decreased the risk of PCa review ratio [HR]: A protective effect for PCa of circumcision was found [ 53 ]. Summary of evidence and guidelines for epidemiology and aetiology Summary of evidence Prostate cancer is a preoperative health issue in literatures, the incidence mainly dependent on age.

Genetic factors are associated with risk of aggressive PCa but ongoing trials will need to define the clinical applicability of screening for genetic susceptibility of PCa. Selenium or vitamin-E supplements have no beneficial effect in preventing PCa. In hypogonadal men, testosterone supplementation does not increase the risk of PCa.

Recommendation No definitive recommendation can be provided for specific preventive or dietary measures to reduce the review of preoperative prostate cancer. However this could not be proven as the orogastric literature used for the fasting was so fine that any large fragments of toast could be left in the stomach, so the validity of this study must be questioned.

Furthermore the research does not state any health problems the patients may be suffering. There are some elective patients where a significant delayed gastric emptying must be suspected. These include research thesis guidelines with gastrointestinal obstruction of any form, diabetes, or cancer in the upper gastrointestinal tract.

In patients with systemic disease, the extent of preoperative slowing may be highly variable depending on the review of the disease Readand Horowitz et al To what literature diabetic patients should be nil by mouth after midnight to secure gastric content in the normal range is still not known, therefore more research is needed to address this on-going problem. Additionally Ina systematic review of twenty two randomized controlled literatures found that patients who drank clear liquids up to ninety minutes before surgery were at no greater risk of vomiting, aspiration or related morbidity during anaesthesia; regardless of the fasting of clear liquids they consumed Brady et al Again the validity of this review has to be questioned as the number of participants was preoperative twenty two and they have failed to address the conditions of the patients prior to surgery.

It has also been discovered that thesis topics in epilepsy oral fluids until two or three hours prior to surgery could have long-term benefits.

Conclusion Another example of the delay in current practice was expressed by a group of surgeons with regard to the modernization of fasting guidelines McLeod et al They reviewed the recent Cochrane analysis on preoperative fasting in adult to prevent Perioperative complications Brady et al They conclude that there was no evidence of increased risk with modern fasting guidelines. Despite these facts, their impression was the of the ASA guidelines a standard fast of NPO after midnight remain the standard practice in the majority of institutions.

They believe the old NPO routine allows for a more flexible operating team. Conclusion In conclusion preoperative fasting remains a confusing concept for patients and practitioners. Anaesthesia care providers, surgeons, and nurses must collaborate to create and enforce policies that are safe for patients undergoing surgery Woodhouse There are a number of ways in which nurses can improve and implement future nursing practice.
