Comparação de valores de PFE em uma amostra da população da cidade de São Carlos, São Paulo, com valores de referência

Abstract

Objective: To compare the reference values for PEF suggested by other authors in 1963, 1989 and 2001 (for populations in the USA, England and Cuba, respectively) with those obtained from a population sample in the city of São Carlos, Brazil, and to determine whether there is concordance among them. Methods: A total of 243 volunteers (123 females and 120 males; 20-70 years of age) participated in the study. The PEF measurements were performed with the volunteer standing, using a nose clip, by means of a portable peak flow meter. These measurements were compared with the reference values using the Friedman test and Dunn's post-hoc test (p < 0.05). Results: Significant differences were found in all age groups from both genders regarding the values predicted in 1989; the same occurred in the 20-30 and 31-40 age groups (both genders), as well as in the 61-70 age group (females only), regarding those predicted in 2001, as well as in the 20-30 age group (males only) regarding those predicted in 1963. Conclusions: The values predicted in 1963 are appropriate for a population of individuals with the same characteristics as the study sample, except for males in the 20-30 age group. Our study is relevant due to the fact that our sample was larger than that evaluated in the 1963 study. The majority of the values predicted in 1989 and 2001 overestimated the PEF values obtained in our study, proving to be inappropriate for the population studied.

Predictive Regression Equations of Flowmetric and Spirometric Peak Expiratory Flow in Healthy Moroccan Adults

“…This is the case for the majority of the studies [2, 7–9, 12–15, 17]. Studies in 2 different cities were rare [3, 18].…”

“…The criteria for inclusion and exclusion of our study were as strict as some studies [7, 20] and more stringent than those of other studies [2, 3, 9, 12, 18, 19]. For example, the Moroccan nationality of any volunteer and of both of his parents was required for inclusion in the study.…”

Peak Expiratory Flow Assessment in Smokers Liabilities

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Silva et al 20 studied the reliability of the PEF meter on the expiratory peak in female smokers and non-smokers, and observed that the female smokers had the lowest PEF compared to non-smokers, concluding that the equipment can be a reliable method to be used in this population. However, the present study did not show differences in PEF in smokers liabilities compared to participants not exposed to ETS, corroborating with our findings that did not show any statistical difference between the groups evaluated.…”

“…[5][6][7] PEF is a measure of pulmonary function and can be defined as the largest flow obtained in a forced expiration from a complete inspiration at the level of Total Pulmonary Capacity (TPC). 5,8,9 Several studies have reported that ETS exposure in adults also results in a significant impairment of pulmonary function. 10,11 Therefore, the aim of this study was to compare PEF in smokers liabilities with participants not exposed to ETS.…”

Skin Tissue Healing Induced by Coherent (Laser) or Non-Coherent (LED) Light Therapy on Aged Rats

“…Some authors observed that, in some cases, LED therapy provided better results than the ones obtained with laser therapy in tendons, skin, bones and ligaments. [7][8][9] Considering the lack of studies about the effect of phototherapy (laser or LED) on the process of skin repair in aging organisms, the objective of this work was to evaluate the efficacy of laser and LED therapy (laser:660nm and 30mW; LED:640nm, 40 nm bandwidth and 54mW) with fluence of 6 J/cm 2 , repeated every 48 h in three applications, on the early wound healing process in the skin of elderly rats compared to controls after 144,312 and 480 h postsurgery.…”
