Harmful Effects

The purpose of this research paper is to investigate whether exercising can reduce the harmful effects caused by smoking. Additionally, the hypothesis of this research study proposes that results will show that the percentage lung capacities of smokers who exercise are similar to non-smokers who don't exercise in which it will prove that exercising does, in fact, decrease the harmful effects of smoking as a smoker who exercises is almost as healthy as a non-smoker who does not exercise. Henceforth, the hypothesis of this research will be accepted. To know that, a questionnaire was prepared, which assisted in placing the individuals in one of 4 groups. The sample size included 152 participants aged 18 and above from the Emirate of Abu Dhabi. A spirometer was used to find the real lung capacity of the participants. The estimated vital capacity was calculated by substituting the height and weight of a person into an equation that gives the body surface area, and then the answer is either multiplied by 2,500 or by 2,000 to find the estimated lung capacity for males or females respectively. After collecting the essential data, it was found that people who smoke and exercise have higher lung capacity than those who smoke but don’t exercise. The t-test was used, and it was found that the difference is significant between those two sets of data. The results imply that exercising could, in fact, reduce the harmful effects of smoking as it has been predicted in the hypothesis. However, in order to be completely free of the risks of smoking, it is highly recommended to quit smoking as well fully.

Physical Capacities

The environment in which they live has a major influence on the development of a person's physical characteristics and abilities. One of the physical capacities that is strongly influenced by the anthropometric measurements of the body and the body's adaptability to the environment is the vital capacity of the lungs. The vital capacity is the maximum volume of air that can enter and leave the lungs during one breathing cycle after maximum inspiration and maximum expiration. This study aims to determine the difference in the vital capacity of the lungs in the people in the lowlands of Mataram city and the highlands of Sembalun village. Sampling was done using purposive sampling technique with a sample of 20 people in each research area with an age range of 21-25 years. The data were collected using a simple spirometer made by the researcher. The control variables in this study included gender, age, height, body weight and sample hemoglobin levels. The results showed the average value of vital lung capacity in the lowlands was 2837.5 ml, while the vital capacity of the lungs in the highlands was 2767.5 ml. The results of hypothesis testing were carried out using the Independent Sample t-test using SPSS 16 and the results of the significance value (2-tailed) 0.740> 0.05 so that Ho was accepted, which means that there is no difference in the vital capacity of the lungs in the highlands and lowlands.

The relationship between body height and body weight has been described by using various terms. Notable among them is the body mass index, body surface area, body shape index and body surface index. In clinical setting the first descriptive parameter is the BMI scale, which provides information about whether an individual body weight is proportionate to the body height. Since the development of BMI, two other body parameters have been developed in an attempt to determine the relationship between body height and weight. These are the body surface area (BSA) and body surface index (BSI). Generally, these body parameters are described as clinical health indicators that described how healthy an individual body response to the other internal organs. The aim of the study is to discuss the use of BSI as a better clinical health indicator for preclinical assessment of body-organ/tissue relationship. Hence organ health condition as against other body composition. In addition the study is `also to determine the best body parameter the best predict other parameters for clinical application. The model parameters are presented as; modeled height and weight; modelled BSI and BSA, BSI and BMI and modeled BSA and BMI. The models are presented as clinical application software for comfortable working process and designed as GUI and CAD for use in clinical application.

In Helix aspersa the ‘cuticle’ on the free surface of the external epithelial cells of the optic tentacles has been shown to consist of a layer of microvilli. Microvilli are also present in the same species on the free cell borders of the body-wall, and in the slug Arion hortensis, on the outer cell surfaces of the external epithelium. In all three cases the microvilli are arranged in a hexagonal pattern. There are indications that branching may possibly occur. The microvilli have granular cores with cross- and longitudinal-striations and there are fibrillar connexions between their tips. On the tentacular and body surfaces of H. aspersa, the microvilli increase the surface area 15 and 12 times, respectively. On A. hortensis the increase in surface area is only 4 times. In H. aspersa, beneath the microvilli on the tips of the optic tentacles there is a layer, about 3 to 4 µ deep, composed of vertical, horizontal, and tangential fibres. Some of these fibres are attached to lamellar bodies, which may have a lipid content. Granules are also found among the fibres. Further, a greater depth of cuticle is found to be present on the tips of the inferior tentacles of H. aspersa than on their sides; this seems to indicate that a fibrillar layer, similar to that on the optic tentacles, may lie beneath the cuticle of microvilli on the tips of the inferior tentacles. A thicker cuticle is also found on the tips of the optic tentacles in other stylommatophoran pulmonates. It has not been found possible to ascertain whether the fibrillar layer is intracellular or extracellular, although the evidence points to the latter. Histochemical tests indicate that mucopolysaccharide is present on the surface of the cuticle. Electron micrographs show a granular precipitate caught on and between the fibrillae connecting the tips of the microvilli. It is suggested that the function of the microvilli is to hold the mucous secretions on the body-surface, which would give protection to the animals.

Abstract Background: Difficult tracheal intubation is a problem commonly encountered by anesthesiologists in the clinic. Methods: In this retrospective study, case-level clinical data and computed tomography images of 96 infants with Pierre-Robin syndrome were included in the analysis. First, computed tomography images were labeled by a clinically experienced physician. Then color space conversion, binarization, contour acquisition, and area calculation processing were performed on the annotated files. Finally, we calculated the correlation coefficient between the seven clinical factors and tracheal intubation difficulty, and the difference in each risk factor under tracheal intubation difficulty. Results: The absolute value of the correlation coefficient between throat area and tracheal intubation difficulty is 0.54, and the difference of throat area under tracheal intubation difficulty is significant. Body surface area, weight and gender also show significant difference under tracheal intubation difficulty. Conclusions: There is a significant correlation between throat area and tracheal intubation difficulty in infants with Pierre-Robin syndrome. Body surface area, weight and gender may have an impact on tracheal intubation difficulty in infants with Pierre-Robin syndrome.

Nasal symptoms often are inconsistent with rhinoscopic findings. However, the proper diagnosis and treatment of nasal pathology requires an objective evaluation of the narrow segments of the anterior part of the nasal cavities (minimal cross-sectional area [MCSA]). The problem is that the value of MCSA is not a unique parameter for the entire population, but rather it is a distinctive value for particular subject (or smaller groups of subjects). Consequently, there is a need for MCSA values to be standardized in a simple way that facilitates the comparison of results and the selection of our treatment regimens. We examined a group of 157 healthy subjects with normal nasal function. A statistically significant correlation was found between the body surface area and MCSA at the level of the nasal isthmus and the head of the inferior turbinate. The age of subjects was not found a statistically significant predictor for the value of MCSA. The results show that the expected value of MCSA can be calculated for every subject based on anthropometric data of height and weight.

Expected mean values and a range of normal values (plus or minus two standard deviations) are presented for the vital capacity and the maximum breathing capacity of male children and adolescents. It is recommended that calculations of the above values be based upon four attributes (age, height, weight, and body surface area) rather than upon a prediction deriving from a single attribute (especially in the individual who does not have a standard height and weight for his age).

The body surface areas of one normal and four extremely obese human subjects have been estimated by three methods: a) direct measurement by a method similar to that which Du Bois described; b) calculation from the Du Bois height-weight formula; and c) calculation from the Du Bois linear formula. The values for the total body surface area of the obese subjects calculated from the height-weight formula varied up to 11% below those that were directly measured. The values for the total body surface area obtained with the linear formula ranged between 13% and 20% above the direct measurements, this being almost entirely due to discrepancies in the trunk and in the thigh estimations. It has been concluded that estimation of the body surface area oxf extremely obese subjects by the Du Bois height-weight formula is satisfactory when considered in relation to the accuracy of the physiologic measurements with which it is generally used. Because of the unusual body form the Du Bois linear formula has been found unsatisfactory for this group. Submitted on March 1, 1960

663 Background: Capecitabine (XELODA) is an orally active fluoropyrimidine that is absorbed intact through the gastrointestinal tract and converted in to 5FU. Standard chemotherapy for advanced colon cancers includes infusional 5FU with leucovorin in combination of oxaliplatin (FOLFOX) or irinotecan (FOLFIRI). With the national shortage of 5FU we had to switch our FOLFOX and FOLFIRI regimens to XELOX or XELIRI. Although in trials the xeloda regimens were non-inferior, the PFS (progression free survival) and OS (overall survival), survival curves tailed behind the infusional 5FU regimens. Methods: At our institution over one month period from August 18th 2011 to September 18th 2011, all patients who were switched from 5FU to xeloda due to national shortage were identified. All charts were retrospectively reviewed identifying patients with colon cancer. Patients with other cancer histologies, were excluded. The charts were reviewed for number of cycles, clinical toxicity, admission to hospital. Results: A total of 90 patients were switched form 5FU to xeloda. 51 had colon cancer. Out of which, 6 (11.7%) patients had the drug discontinued due to toxicity and 4 out of the 6 required hospitalization due to adverse effects of xeloda, mainly diarrhea and vomiting. 80% of these had left sided colon cancer and 50% each received oxaliplatin and irinotecan respectively. The total number of hospitalization days was 20. The average wholesale price (AWP) of one cycle of xeloda for body surface area range from 1.5m2 to 2m2 ranges from 2605.68$ to 3474.24$ for every 3 week cycle. In comparison the corresponding AWP for 2 cycles of 5FU over a month is 51.81$ to 69.08$. This would become a net higher price of 2553.87$ to 3405.16$ for BSA of 1.5 to 2m2 per month for the switch to xeloda. There were 51 patients who received xeloda at least one cycle which costed about 151,954.50$ if we average the body surface area. Additionally there were 20 admission days costing about 50,000$, making the net costs of switching to xeloda more than 200,000$ in a single month. Conclusions: Although xeloda is non-inferior to 5FU and can be a substitute, left sided colon cancers tend to do have more adverse effects. Additionally Xeloda is associated with higher administration costs.
