Opis:: Objectives: To assess the effect of exposure to flour dust on pulmonary function tests, prevalence of symptoms (respiratory, allergic/irritating) and parameters of allergic sensitization in terms of skin prick test, and bronchial hyper-responsiveness. Material and Methods: 43 bakers (with at least 2 years of occupational exposure) working at different bakeries in Ismailia city, Egypt; and 64 control subjects of comparable socio demographic characteristics were compared. All participants were subjected to an interview questionnaire, clinical chest examination, skin prick test, bronchial hyper-responsiveness test and measurements of pulmonary function parameters. Results: All respiratory and allergic symptoms were more prevalent among bakers compared to the control group, with the highest odds ratio for allergic symptoms (OR = 6.9; p < 0.0001) and dyspnea (OR = 6.3; p = 0.0004). Bakers had a higher percentage of SPT positive results with statistically significant difference between the two groups (p < 0.0001). Bakers had lower observed values compared to the control group with statistically significant difference for FVC, FEV₁/FVC ratio, $ \text{FEF}_\text{75%} $, and $ \text{FEF}_\text{25-75%} $ parameters. Conclusion: The present study suggested that occupational exposure to flour dust may affect respiratory irritation and sensitization, and reduce the pulmonary function tests such as FVC, FEV₁, and FEV₁/FVC ratio and $ \text{FEF}_\text{25-75%} $.

Opis:: Background. The aim of this study was to determine the impact of the level of physical activity on pulmonary function in patients with pectus excavatum. Material and methods. This study included 47 patients diagnosed with pectus excavatum, with a median age of 19 years (min. 17 years, max. 26 years). The degree of deformity was evaluated clinically by anthropometric measurement. Spirometry was used for the evaluation of pulmonary function. The demographic, clinical data, and experience of patients with sporting activity were examined using a questionnaire. The self-reported International Physical Activity Questionnaire short form (IPAQ-SF) was used to determine physical activity levels. Results. With higher physical activity, there was statistically significant higher inspiratory vital capacity (IVC) (rho=0.628), forced vital capacity (FVCex) (rho=0.455), and forced expiratory volume in 1 second (FEV₁) (rho=0.356). A statistically significant relationship was observed between deformity rate and spirometric parameters for FEV₁ (p=0.011), maximal expiratory flow rate of 75% FVC (MEF75) (p<0.0001), and peak expiratory flow (PEF) (p<0.0001). Conclusions. Respiratory functions of patients with chest deformity are positively influenced by physical activity.
Wprowadzenie. Celem badania było ustalenie wpływu poziomu aktywności fizycznej na funkcje płuc u pacjentów z lejkowatą klatką piersiową. Materiał i metody. W badaniu wzięło udział 47 pacjentów ze zdiagnozowaną lejkowatą klatką piersiową. Średnia wieku wynosiła 19 lat (minimum 17, maksimum 26 lat). Stopień deformacji został określony klinicznie za pomocą pomiaru antropometrycznego. Do określenia funkcji płuc zastosowano spirometrię. Dane demograficzne, kliniczne oraz związane z aktywnością sportową pacjentów zostały zebrane w postaci ankiety, natomiast w celu ocenienia poziomu aktywności fizycznej wykorzystano skrócony Międzynarodowy Kwestionariusz Aktywności Fizycznej (IPAQ-SF) wypełniony przez pacjentów. Wyniki. Wraz ze wzrostem aktywności fizycznej pacjentów zaobserwowano statystycznie istotny wzrost wdechowej pojemności życiowej (IVC) (rho=0,628), natężonej objętości wydechowej (FVCex) (rho=0,455) i objętości wydechowej pierwszosekundowej (FEV₁) (rho=0,356). Zaobserwowany związek pomiędzy stopniem deformacji i parametrami spirometrycznymi okazał się statystycznie istotny dla zmiennych: FEV₁ (p=0.011), maksymalnego przepływu wydechowego o 75% FVC (MEF75) (p<0,0001) i szczytowego przepływu wydechowego (PEF) (p<0,0001). Wnioski. Aktywność fizyczna ma pozytywny wpływ na funkcje oddechowe pacjentów z deformacją klatki piersiowej.

Tytuł:: Allergic and nonallergic rhinitis in schoolchildren: part II : relationship to spirometric parameters, bronchial hyperresponsiveness and biomarkers of allergic inflammation
Autorzy:: Twarduś, Krystyna
Lis, Grzegorz
Opis:: In recent years, with the increasing prevalence of allergic rhinitis (AR), a higher incidence of nonallergic rhinitis (NAR) has been observed. Aim: The aim of the study was the comparison of pulmonary function tests and the degree of bronchial hyperresponsiveness (BHR) in children with AR and NAR, evaluation of the biomarker for clinical AR or BHR diagnosis. Material and methods: Pulmonary function tests and BHR in the exercise tests were done in 139 schoolchildren (8-14 years of age) with symptoms of non-infectious rhinitis. The analyzed biomarkers included exhaled nitric oxide (FeNO), total IgE (tIgE), serum IL-4, serum tumour necrosis factor α (TNF-α), absolute eosinophils count in blood (Eos). Positive prick tests with 10 aeroallergens identified children with AR. Results: Spirometric parameters and values of BHR were not different in AR (n = 73) and NAR (n = 66) groups. The risk of BHR was higher in children with AR than those with NAR (OR = 2.768; p = 0.051). In the logistic regression analysis, none of the analyzed biomarkers was related to BHR. Differences in the area under the ROC curve (AUC) for: tIgE and FeNO (AUC tIgE-AUC FeNO = 0.102; p = 0.042), FeNO and Eos (AUC FeNO-AUDEos = 0.07; p = 0.219), tIgE and Eos (AUC tIgE-AUC Eos = 0.172; p = 0.002) showed that measurements of tIgE level were the best diagnostic tool for AR (sensitivity = 78.9%, specificity = 79.4% for tIgE = 68 kU/l). Conclusions: There were no differences in pulmonary function test parameters between groups of children with AR and NAR. Bronchial hyperresponsiveness was more often observed in AR than in NAR. Any biomarker of allergic inflammation predicts BHR in children with rhinitis. The accuracy of diagnostic AR testing with tIgE measurement (cut-off level = 68 kU/l) was moderately good in schoolchildren.

Opis:: The purpose of the present study is to assess the physique and fitness status of young school and college age swimmers from West Bengal. This cross sectional study was carried out on 46 male and 9 female swimmers of 9-20 years of age. The study parameters include body height, body weight, BMI, different anthropometric parameters, skinfold thickness and aerobic power, strength, flexibility, blood pressure and pulmonary function. Besides, history of training was taken by questionnaire. In the present study male and female adolescent swimmers have significantly higher body fat than their non-swimmer counterparts. Besides, respiratory capacity, max. oxygen consumption and flexibility parameters are significantly higher in male and female swimmers than in control group boys and girls. Besides, highly significant correlation has been found between sitting height, arm span and hand span of swimmer with swimming speed, years of training(swimming) and percentage of body fat. Again, pulmonary function, strength and max. oxygen consumption parameters are significantly correlated with years of training and speed of training. Therefore, simple regression equations are constructed to predict strength, respiratory and cardio-vascular parameters of adolescent swimmers on the basis of years of swimming and speed of swimming. When different style of swimming is considered it has been observed that highest Vo2 max value has been found in free style and butterfly swimmers followed by breast stroke and then back stroke swimmers. Swimmers of the present study when compared to international standard, they are shorter and lower in body fat content values and some physiological parameters like Vo2 max, flexibility and hand grip strength than international standard values. From this study it can be concluded that as there is no available information regarding strength, cardiovascular and respiratory status of adolescent girls and boys swimmers of West Bengal, this study can be said to be a pilot study on the basis of which further elaborate investigation requires to be initiated. Thus these baseline information of physique and physiological parameters of adolescent swimmers will provide local database for coaches and sports physiologists to develop proper training schedule and for identification of talent in the early ages.

Opis:: Background: Jute industry workers constantly exposed themselves to jute dust and are at risk of impairment of lung function. Investigation on various studies revealed the effects of exposure to jute dust but limited studies so far undertaken regarding its bearing on pulmonary function of jute workers of West Bengal,India. Purpose: To evaluate the respiratory status of jute mill workers of West Bengal exposed to occupational hazards. Materials and Methods: This cross sectional study was conducted on 203 male jute mill workers of age range 18 – 60 yrs. from West Bengal and a control group of 141 men of similar age .Dynamic pulmonary function parameters were carried out including physical parameters, respiratory abnormalities, year of exposure and smoking history. Results: FVC, FEV1, FEF 200-1200 and PEFR values of higher age group non smoker of low dust zone were significantly higher in comparison to the non smoker of high dust zone. The prevalence of chest tightness was 33.49% and liver dysfunction was 41.9% in dusty zone workers of jute mill in comparison to less dusty zone. Again, incidence of chest tightness and cough was highest (35.44%) in higher age group workers and prevalence of byssinosis like symptoms and chronic bronchitis was 30- 37% after 10 – 30years of exposure. But occurrence of bronchial asthma was 11.9% in workers of greater than 20 years of exposure. Prevalence of all the above respiratory abnormalities was higher among smokers than non-smokers. Conclusions: Concentration of jute dust exposure had been associated with decrease in FVC, FEV1, and PEFR with a higher risk of developing chronic bronchitis, bronchial asthma, byssinosis and other respiratory symptoms. This indicated high occupational health hazards which would create an alarming situation, if remained unchecked.

Opis:: ObjectivesSilicosis is a chronic occupational lung disease. As was previously found by the authors, some proteins increased in the lung tissue of activated rats, and protein tyrosine phosphatase non-receptor type 2 (PTPN2), factor B, and vaccinia-related kinase 1 (VRK1) showed highly differential expressions.Material and MethodsIn this study, serum and bronchoalveolar lavage fluid samples were collected from patients with silicosis and healthy people to verify the expression of PTPN2, factor B, and VRK1. The diagnostic value of differentially expressed proteins for silicosis was judged.ResultsThe expression levels of serum PTPN2, VRK1, and factor B in patients with silicosis were significantly higher than those in the control group (p < 0.01). Higher serum PTPN2 and factor B concentrations significantly and negatively correlated with the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV₁/FVC), maximum vital capacity (VC_max), FEV₁, and FVC, suggesting that the high expression of PTPN2 and factor B is associated with decreased pulmonary ventilation function and restrictive ventilatory impairment in patients with silicosis. All area under curve (AUC) measurements generated from single detection events were >0.744, with PTPN2 reaching the highest value (0.858). The AUC, sensitivity, and specificity for the combined diagnosis using factor B and PTPN2 were 0.907, 86.91% and 85.07%, respectively, for factor B and PTPN2. The 3 differentially expressed proteins are potential classes of predictive biomarkers for silicosis.ConclusionsRegarding the economy and test practicality, the best diagnostic combination is factor B and PTPN2 for the analysis of AUC, sensitivity and specificity.

Opis:: Background The photocopying occupation contributes to various health issues in workers. Elevated levels of oxidative stress have been found to be associated with respiratory problems in occupational workers. The intention of the current research is to evaluate the association between the pulmonary function parameters, a biomarker of oxidative stress, and the photocopying occupation in Lahore, Pakistan. Material and Methods The study was performed on a group of photocopying operators (N = 100) and a control group (N = 100). A structured questionnaire was developed to gather the demographic attributes. Lung function testing was done with the spirometer. The blood lipid peroxides level, as thiobarbituric acid reactive substances (TBARS), was assessed spectrophotometrically. Results A statistically significant reduction was found in the pulmonary function parameters as compared to the control group. In the study group, the prevalence of respiratory symptoms, including cough (31%), sneezing (18%), wheezing (9%) and breathing issues (19%), was high as compared to the control group. A significantly higher plasma TBARS concentration was observed in the photocopying workers. A negative correlation prevailed between FVC (−0.081), FVC% predicted (−0.038) and FEV1 (−0.043), and the duration of exposure. Conclusions The study showed that the occupational exposure could have a significant effect on the normal pulmonary function and the oxidative potential of well-being. The profound emissions in the vicinity of photocopying centers may be responsible for the variations in the pulmonary function parameters and oxidative stress. Med Pr. 2019;70(4):403–10

Opis:: Introduction: Information on the changes of pulmonary function and the right cardiac structure in patients with coal worker’s pneumoconiosis in China is very scarce. This study was performed to clarify the changes of pulmonary function and right cardiac structure in patients with coal worker’s pneumoconiosis in China. Material and methods: Pulmonary function, pulmonary artery systolic pressure, and the right cardiac structure were evaluated by spirometry and color Doppler echocardiography. Results: The pulmonary artery systolic pressure of patients with coal worker’s pneumoconiosis was increased with disease severity. Patients with coal worker’s pneumoconiosis also exhibited an impaired pulmonary function and altered right cardiac structure compared with control subjects. A significant linear correlation of the variables of pulmonary ventilation and diffusion function with the indicators of the right cardiac structure was found in patients with coal worker’s pneumoconiosis in China. Conclusions: This study elucidated a deterioration of pulmonary function and right cardiac structure in patients with coal worker’s pneumoconiosis in China.

Opis:: Badanie freeflowmetryczne (FFM) pozwala na ocenę wpływu techniki wydechu na wartości parametrów oddechowych. W niniejszym projekcie wykorzystano badanie FFM w celu zbadania mechanizmów zmian zachodzących w układzie oddechowym na skutek treningu pływackiego. Stwierdzono, że zastosowanie wydechu przez zasznurowane usta i przez nos istotnie redukuje pułapkę powietrzną. Pozwala to przypuszczać, że przyczyną występowania pułapki powietrznej u pływaków może być wiotkość dróg oddechowych.
Freeflowmetry allows to evaluate influence of exhalation technique on spirometric parameters. This project uses freeflowmetric examination to explore the changes occurring in respiratory tract of young swimmers. We found that pursed lips breathing and nose breathing significantly reduces air trapping. Therefore, it is possible that air trapping in swimmers may be caused by limpness of respiratory tract.
