Full textAbstract:
The results of numerous medical studies and kinesiology research show the existence of differences in the pulmonary function with reference to age, body height and size and the relation of certain parameters of body composition. The aim of this research is to determine eventual differences in the health and pulmonary function with soldiers of different age. The sample of examinees consisted of 240 members of Montenegro Armed Forces, having between 18 to 57 years of age, divided into 8 subsamples of 30 examinees each (following the age category). The sample of measures were made of the following indicators of pulmonary function: 1) Forced Vital Capacity, 2) Forced Expiratory Volume in 1 second, 3) the proportion of Forced Expiratory Volume in 1 second and the Forced Vital Capacity and 4) Peak Expiratory Flow. The central and dispersion parameters of variables were calculated for all variables. For examining the potential differences between the subsamples of examinees, and for determining the actual source of variability between the groups, multivariate and univariate analysis of the variance were applied, as well as the post hoc test with Tukey's model. Statistically significant differences were determined in pulmonary function compared to the age of soldiers. The pulmonary function of soldiers from 18 until 21 years of age differ from the soldiers of the next three age categories. Also, were determined that the next three variables mostly contribute to that difference: Forced Vital Capacity, Forced Expiratory Volume in 1 second and the Peak Expiratory Flow. In the Forced Vital Capacity were determined relatively constant values were detected from 32 until 52 years of age of the soldiers. The obtained results confirm the effect of numerous specific factors in the system of functioning of the military organization.

Background/Aims Neurological dysfunction from stroke affects not only the muscles of the extremities and trunk, but also the respiratory function, so it is important to improve the respiratory function of patients with stroke is recognised as an important part. The aim of this study was to investigate the effects of diaphragmatic and pursed lip breathing exercises on pulmonary function, chest expansion and walking endurance in older patients with chronic stroke. Methods The participants were 32 older patients with chronic stroke, randomly assigned to two groups. The study group (n=16) performed diaphragmatic breathing exercises in combination with pursed lip breathing exercises, while the control group (n=16) performed non-resistant cycle ergometer exercises. Forced vital capacity, forced expiratory volume in 1 second, the ratio of forced expiratory volume in 1 second FEV1 to forced vital capacity, peak expiratory flow, chest expansion and 6-Minute Walk Test measurements were taken before and 4 weeks after treatment. Results The breathing exercise group exhibited a significant increase in chest expansion and 6-Minute Walk Test outcome measurements (P<0.05). There was a significant difference in forced vital capacity, forced expiratory volume in 1 second and peak expiratory flow between the two groups (P<0.05). Conclusions Diaphragmatic breathing and pursed lip breathing exercises were effective in improving pulmonary function in older patients with chronic stroke.

Full textAbstract:
The study evaluated key spirometric parameters in patients with post-tuberculosis (post-TB) lung sequelae after recovery from a new coronavirus infection. The main group incliuded 14 patients with clinically cured respiratory tuberculosis who had recovered from the new coronavirus infection and, after recovery, were sent to the Glukhovskaya tuberculosis sanatorium for treatment in 2020-2021. The control group included 52 patients with residual post-TB sequelae, who did not have a new coronavirus infection and who were treated at the sanatorium during the same period. The groups were comparable in terms of epidemiological and clinical criteria, except for post-TB sequelae: the main group included 13 cases (92.9%) of minor post-TB sequelae, 1 case (7.1%) of major post-TB sequelae, and the control group included 36 (69.2%) and 16 (30.8%) cases, respectively. Pulmonary function tests included vital capacity, forced vital capacity, forced expiratory volume in 1 second, and forced expiratory volume in 1 second/forced vital capacity. Tests were performed at admission to the sanatorium and after 1 month. At stage 1 in the main group, vital capacity, forced vital capacity and forced expiratory volume in 1 second were on average below the predicted level (80%) compared with the control group, and after sanatorium treatment the same parameters improved slightly. In the control group, the initial indicators were significantly higher, the rates of recovery of vital capacity of the lungs and forced vital capacity of the lungs were comparable with the main group, during the 2nd examination, the average levels of recovery of vital capacity of the lungs and forced vital capacity of the lungs approached, and in terms of forced expiratory volume in the 1st second, they reached the norm. At baseline, low ventilatory lung capacity correlated with clinical symptoms, as 42.8% of patients in the main group and 55.7% of controls reported shortness of breath. However, after sanatorium treatment, the control group more often showed parameters below 60%: 7.7% of cases for vital capacity, 17.3% for forced vital capacity, 11.5% for forced expiratory volume in 1 second, while the main group showed mostly slight or moderate decrease of these parameters. Therefore, the new coronavirus infection has a negative impact on the functional capacity of the respiratory system, but major post-TB sequelae also contribute to the development of ventilatory disorders.

Full textAbstract:
Background. Besides the extensive regulatory role in growing number of biologic processes, vitamin D has been recently considered essential for lungs function as well as protective against exacerbation of chronic obstructive pulmonary diseases. We assessed the correlation between vitamin D serum levels with pulmonary function in healthy individuals. Methods. In a cross-sectional study, healthy volunteer (n=92) participants underwent the following laboratory procedures: a blood test, a 24-hour urine collection test, and the serum level of 25-hydroxy vitamin D before undergoing spirometry. Linear correlation coefficient was calculated to detect the association between serum level of 25-hydroxy vitamin D and pulmonary volumes. Results. The mean age of participants was 39.95±9.98 years. 48% of participants showed different levels of 25-hydroxy vitamin D deficiency. We recognized a consistent direct positive correlation between serum levels of 25-hydroxy vitamin D and lung function volumes. The coefficient for forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25–75%, and forced expiratory volume in 1 second/forced vital capacity ratio were 0.610, 0.509, 0.454, and 0.551, respectively. Conclusions. Our findings suggest correlation between higher serum levels of 25-hydroxy vitamin D and improved pulmonary function. Accordingly, supplemental vitamin D might significantly improve treatment response.

Full textAbstract:
Background: Air conditioners are used extensively these days of the modern lifestyle. Inhalation of cold dry air while using Air conditioners causes bronchoconstriction due to which alteration may occur in pulmonary function. This study was aimed to compare the Pulmonary Function tests of Car AC users and non AC users. Methods: The Study included 52 employees not exposed to car air conditioner as a control (group I) and 52 employees exposed to car air conditioner with minimum exposure of 1 hour per day for 6 months as a subject (group II). Pulmonary function tests were performed using computerised spirometer. Statistical analysis was done by unpaired t test.Results: Age, Height and weight are not statistically significant between study group and control group. Forced vital capacity, forced expiratory volume in 1 second, Ratio of Forced vital capacity and Forced expiratory volume in 1 second, Inspiratory reserve volume, Expiratory reserve volume, Maximum voluntary ventilation are decreased in car air conditioner users compared to non-users, but was not significant. Forced expiratory flow (FEF), Peak expiratory flow rate (PEFR) values shows statistically significant decreased in car air conditioner users.Conclusions: The present study shows hyper-responsive airways on exposure to cold air which leads to bronchoconstriction. The significant decrease in PEFR, FEF suggest that upper airways as well as smaller airways are affected on exposure to car AC. So, Exposure to car Air Conditioner leads to risk of developing respiratory dysfunction.

Background/Aims Mucus hypersecretion and altered lung functions leads to adverse clinical outcomes in chronic obstructive pulmonary disease. The aim of this study was to compare the effects of the Lung Flute and threshold positive expiratory pressure devices on sputum quantity and pulmonary functions in chronic obstructive pulmonary disease patients. Methods A total of 50 patients with chronic obstructive pulmonary disease were randomly divided into two groups. Group 1 used the Lung Flute device and group 2 used a threshold positive expiratory pressure device. Sputum quantity was measured post-intervention on a daily basis. Forced expiratory volume in the first second, forced vital capacity, and peak expiratory flow rate were evaluated on day 1 and day 6. Results The mean sputum quantity in group 1 was 11.40 ml and it was 11.04 ml in group 2. Between-group comparison demonstrated a significant improvement in forced expiratory volume in the first second for group 1 compared to group 2 (P<0.005). Conclusions The Lung Flute was found to be slightly more effective than the threshold positive expiratory pressure device for airway clearance and also had a positive effect on pulmonary functions in patients with chronic obstructive pulmonary disease.

Full textAbstract:
Mycoplasma pneumoniae (MP) is defined as a common cause of pulmonary infections and accounts for up to four over ten of pneumonia in children over age 5. This study was aimed to explore the diagnosis and prognosis of mycoplasma pneumoniae pneumonia (MPP) in children using high-resolution computed tomography (CT) (HRCT). 71 children hospitalized with MPP were undertaken as the research objects to observe the incidence rate, occurrence time, and duration of the clinical symptoms and pathological signs. The chest HRCT and pulmonary ventilation function (PVF) were examined in the acute phase, the second phase re-examination period, and the third phase re-examination period. Relevant indicators were statistically analyzed to determine the change rules of chest HRCT and PVF and correlation between the two. Clinically, the children with MPP suffered from fever, cough, and sore throat. In addition to the above symptoms, children with MPP had different degrees of PVF impairment. Compared with the group with normal HRCT results, the forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), forced expiratory flow at 25% forced expiratory volume (FEF25), forced expiratory flow at 50% forced expiratory volume (FEF50), forced expiratory flow at 75% forced expiratory volume (FEF75), and maximum mid-expiratory flow (MMEF75/25) of children in bronchopneumonia group, segmental pneumonia group, and lobar pneumonia group were obviously reduced, showing statistically great differences (P < 0.05). Compared with the case in acute phase, the PVF indicators of children in the re-examination phases were much higher, with greatly statistical differences (P < 0.05). In children with MPP, both the large and small airways were affected, but the recovery of the small airways was slow. Pulmonary HRCT and PVF can be undertaken as important indicators to judge the severity and prognosis of MPP in school-age children.

Introduction. The pathogenetic differences between the phenotypes of occupational chronic obstructive pulmonary disease which develop after silica-containing dust exposure are still unclear. The research aims to study the relationship of occupational chronic obstructive pulmonary disease clinical phenotypes with inflammation. Material and methods. 123 patients were included in the study. Basing on the forced expiratory volume in 1 second, clinical symptoms and the history of exacerbations, the patients were divided into 4 groups (group 1 - 30 people (24%) phenotype «B1», group 2 - 16 people phenotype «B2» (13%), group 3 - 32 people (26%) phenotype «D», group 4 - 45 people (36%) phenotype «A»). The groups of patients were comparable in age, body mass index, duration of working period in hazardous conditions, the number of cardiovascular comorbidities (p>0.05), but differed in spirometry, the number of exacerbations and the number of eosinophils in the blood (p = 0.02, p = 0.0001 and p=0.006) and therapy. Results and discussion. The concentration of hyaluronic acid in the blood serum was increased in all groups of the patients, but most of all in the «D» phenotype, 204.5 ng/ml, p=0.0024. Immunoglobulin A was above the normal level in the patients with phenotypes «B2» and «D»6,32 and 9.84 mg/l, p=0.0059. Endothelial synthase in phenotypes «B2» and «D» was more than 2 times higher than in other groups (57.9 and 64.5 pg/ml, р=0.013). The groups did not differ in terms of endothelin-1. Correlation analysis revealed statistically significant (p<0.05) correlations between exacerbations, eosinophils, comorbidities, forced expiratory volume in 1 second. Immunoglobulin A had a direct relationship with endothelial synthase and an inverse relationship with forced expiratory volume in 1 second. Hyaluronic acid directly correlated with the number of exacerbations and eosinophils and inversely with forced expiratory volume in 1 second. Endothelial synthase had a direct relationship with eosinophils and cardiovascular comorbidities and an inverse relationship with forced expiratory volume in 1 second. Conclusion. The concentration of hyaluronic acid, immunoglobulin A and endothelial synthase in the blood serum reflects the activity of remodelling bronchi, the risk of exacerbations and connections to cardiovascular comorbidities.

Background:The use of spirometry in the assessment of children with asthma is taking on new importance with the realization that considerable airway obstruction may exist in the absence of clinically detectable abnormalities. Hence this study was planned to evaluate, forced expired volume in 1 second (FEV1), forced vital capacity (FVC), the forced expiratory flow between 25% and 75% of vital capacity (FEF25-75) and Peak Expiratory Flow rates (PEFR) in asthmatic children aged 6-12 years. The objective of the study was to determine prevalence of asthma according to clinical classification and identify common trigger factors and to determine which is more sensitive between FEV1, FVC, FEV1/FVC, FEF 25-75 and PEFR in different age groups.Methods: The present study was conducted among 60 patients of age group 6 to 12 years with asthma. Forced vital capacity (FVC), Forced expiratory volume in 1 second (FEV1), Ratio of forced expiratory volume in 1 second and forced vital capacity (FEV1/FVC), PEFR and Forced expiratory flow between 25-75% were recorded. Data was analyzed using chi-square test, Karl Pearson’s correlation coefficient. Level of significance was set at 5%. All p values less than 0.05 were treated as significant.Results:In Age and Sex wise correlation with classification of asthma, a male preponderance was seen in all the age groups i.e. between 6-8 years, 9-10 years and 11-12 years. Mosquito coils were the most common indoor agents to trigger an asthmatic accounting for nearly 80%. Amongst the outdoor triggers, exacerbation of symptoms during the cold weather accounted for 90 % followed by variation during festivals like Diwali, dust, pollution, exercise and insects. Comparison of Pre and Post bronchodilator FEF 25-75 values have shown a high statistical significance.Conclusions:Parents need to be educated regarding certain modifiable factors that can improve the prognosis. Pulmonary Function tests should be performed as a routine office procedure. Peak expiratory flow meter is a handy instrument. In all children above 6 years of age suspected to have asthma, this test should be performed before beginning therapy.

Background: A few data are available on the effects of pregnancy on pulmonary function in different countries. But no such established data are available in our country. So we designed this study in our population. Objectives: To observe the forced expiratory volume in first second (FEV1) and ratio of forced expiratory volume in first second and forced vital capacity (FEV1/FVC%) in different trimesters of normal pregnant women and to compare them with those of healthy non-pregnant women. Materials and Methods: This observational and analytical study was carried out in the department of Physiology, Dhaka Medical College during July 2004 to June 2005. Total 100 women aged from 25 to 35 years without any recent history of respiratory tract diseases were selected as study population. Among them, 75 normal pregnant women were taken as experimental and 25 healthy non-pregnant women were taken as control groups. The experimental group included 25 pregnant women in first trimester, 25 in second trimester and 25 in third trimester. Forced expiratory volume in first second (FEV1), ratio of percentage of forced expiratory volume in first second and forced vital capacity (FEV1/FVC%) were measured in pregnant and non-pregnant control women. The FEV1 and FEV1/FVC% were measured by using an automatic spirometer. Statistical analyses were done by unpaired Students t test between the study groups and p value <0.05 was taken as significant.Results: The mean ± SD of measured values of FEV1 were 2.41 ± 0.87, 2.28 ± 0.59, 2.15 ± 0.74 and 1.89 ± 0.76 liters in non-pregnant women and in pregnant women during first trimester, second trimester and third trimester. The mean ± SD of measured values of FEV1/FVC% were 75.22 ± 16.77, 74.86 ± 11.06, 74.42 ± 17.43 and 71.81 ± 15.87% in nonpregnant women and in pregnant women during first trimester, second trimester and third trimester. Conclusion: The FEV1 and FEV1/FVC% were significantly lower in third trimester pregnant women than that of non-pregnant and first trimester of pregnant women and FEV1/FVC% gradually decreased from first to third trimester of pregnant women.

Introduction and Aim:One of the most utilized parts of the body when playing a wind instrument is diaphragm. It assists to blow air in and out of your lungs and into the instrument to create sound. Using controlled and measured breaths, the breathing and lung capacity could get improve. Even, music therapy, such as playing wind instrument has been used as a technique for managing and fastening recovery on a physical and emotional level.Therefore, aim of this study was to determine the effects of respiratory muscle training with wind instrument among obese individuals. The objective was to find out the effects of respiratory muscle training with wind instrument in improving maximum voluntary ventilation, forced expiratory volume in 1 second, forced vital capacity and reducing dyspnoea among obese individuals.
 
 Materials and Methods: Study included 40 individuals with obesity aged 18-30years. Participants were equally divided into 2 groups- A and B. Group A treated with wind instrument (flute) and group B treated with incentive spirometer, both the groups were treated for 5 days a week for 5 weeks in which 1 session per day for 40 minutes with 5 minutes of warm up, 10 minutes of breathing training, 20 minutes of intervention training program and 5 minutes of cool down. Both the groups were tested for maximum voluntary ventilation, forced expiratory volume in 1 second, forced vital capacity using spirometry and dyspnea was graded with modified borg scale as a pre-test and post-test.
 
 Results: The comparison of pre and post-test values of maximum voluntary ventilation, forced expiratory volume in 1 second, forced vital capacity and modified borg scale showed a statistically significant difference with p-value <0.0001. While comparing the post-test values of maximum voluntary ventilation, forced expiratory volume in 1 second, forced vital capacity and modified borg scale between group A and group B, group A showed higher result with statistical significant difference of p-value <0.0001.
 
 Conclusion: Playing a wind instrument was found to be more effective than respiratory training using an incentive spirometer.

Background: Body posture refers to the position of a person’s body in space, the alignment of body parts in relationship to one another and to the environment at one point in time. Different postures such as forward head posture and kyphosis have been shown to alter breathing mechanism. Pulmonary function test is an important tool in the investigation of patients with respiratory pathology. Methods: A comparative study was conducted at vikhe patil memorial hospital and college, Ahmednagar. The craniovertebral angle and Pulmonary function test was taken on 40 adults. Results: The study show that Forced vital capacity, forced expiratory volume in 1 second and Peak Expiratory Flow Rate were significantly lower in the forward head posture group than in the normal group. The FEV1/FVC ratio was more in the forward head posture group than in the normal group. A positive correlation was observed between the Craniovertebral angle and the forced Expiratory Volume in 1 sec (r=0.058). while a negative correlation was observed between the Craniovertebral angle and Forced Vital Capacity (r=–0.012) and also observed between the Craniovertebral angle and Peak Expiratory Flow Rate (r= -0.189). Conclusion: The pulmonary functions showed significant reduction in Young adults with Forward head posture as compared to normal craniovertebral angle. There is positive correlation was observed between the Craniovertebral angle and the forced Expiratory Volume in 1 sec. while a negative correlation was observed between the Craniovertebral angle and Forced Vital Capacity and between craniovertebral angle and Peak Expiratory Floe Rate.

Full textAbstract:
Nocturnal asthma is defined by a drop in forced expiratory volume in 1 second (FEV1) of at least 15% between bedtime and awakening in patients with clinical and physiologic evidence of asthma. Nocturnal asthma is associated with a circadian pattern in lung function, distal airway inflammation, glucocorticoid receptor affinity, pulmonary capillary blood volume, and beta-2 adrenergic receptor function may also contribute. Knowledge of these characteristics, along with an understanding of the specific therapies directed at the circadian nature of this disease, can result in significant improvements in lung function, sleep quality, and asthma related quality of life.

Full textAbstract:
Background: Second-hand smoking or environmental tobacco smoke is a critical health risk. Children are the most vulnerable to second-hand smoking because of their small bronchial ducts, less developed immunity, and low-physical activity.
 Objectives: The purpose of this study was to ascertain the effects of second-hand smoking on lung functions in athlete and non-athlete school-aged children.
 Methods: This observational study included forty-six school-aged children, their age was 8-15 years, assigned to three groups; 2 study groups and 1 control group (n=15). The study groups comprised of 16 football players, and of 15 cyclists. Lung func- tions were evaluated recording forced vital capacity, forced expiratory volume in 1 sec and peak expiratory flow using digital spirometer.
 Results: All measures were recorded in definite values and the children were also classified into second-hand smoking (SH), or non-exposed to tobacco smoking (NE). The findings presented a significant increase (p<0.05) of the study groups in forced vital capacity, forced expiratory volume in 1 sec and peak expiratory flow solely for the non-exposed children. However, there were non-significant differences between the cyclists and football players or between the passive smoking children and non-exposed children in any of the two study groups (p>0.05).
 Conclusion: The outcomes of this study suggest beneficial influences of the sports activity on the lung functions, without dif- ferent influences of the cyclists and football players on the lung functions.
 Keywords: Children; second-hand smoking; lung functions; athlete.

The study aims to assess the relationship between the body structure, physical fitness, and functional parameters of the respiratory system of the cadets from the General Tadeusz Kościuszko Military University of Land Forces (AWL) and their results in passing selected obstacle courses. The research material was collected from testing cadets of the third year of management studies. The research included anthropometric measurements, physical fitness tests, spirometry, and tests determining the level of passing selected obstacle courses. Body height and weight were measured. The body mass index was also calculated. Besides, the following functional characteristics were measured: cardiopulmonary endurance, functional strength, running speed and agility, balance, forced expiratory volume in 1 second, forced vital capacity, and peak expiratory flow. The study also included tests determining the level of passing the land and water obstacle courses. Statistically significant relationships were found between height and weight, balance, and forced expiratory volume in 1 second. Moreover, there were correlations between body weight and body mass index and the results in passing the land obstacle course. In addition, there were connections between cardiopulmonary endurance and performance in passing the land obstacle course, body balance, and performance in passing the land and water obstacle course. All the relationships mentioned above were low and statistically significant.

Full textAbstract:
A questionnaire was sent to all pediatric training programs to evaluate the use of pulmonary function reference standards and the interpretation of pulmonary function test results. Responses were obtained from 107 of 130 institutions, and 94 of these had pulmonary function laboratories available. Of the 94, 60 used one of three reference standards. The primary reason the reference standards were chosen was either unknown or because they came with the spirometer (24), were recommended by another person or were those used in that person's training (34), or were thought to be the best standards available or most applicable to the population to be tested (31). To define abnormality, most used an 80% predicted cutoff for forced vital capacity, forced expiratory volume in 1 second, and forced expiratory flow at 25% to 75% vital capacity. For a change in an individual through time, most used a 10% change for forced vital capacity, forced expiratory volume in 1 second, and forced expiratory flow at 25% to 75% vital capacity. Thirteen used statistical methods to define abnormal individuals and none used statistical methods to define a significant change over time. Although there are a few guidelines for reference standards and interpretations of pulmonary function tests, it appears that most laboratories are not using those guidelines and that further guidelines and education are needed.

Background Macrolides exert anti-inflammatory and immunomodulatory effects beyond their purely antibacterial action, as demonstrated by several bronchial inflammatory disorders, including asthma. Methods Fifty-eight children with newly diagnosed mild persistent asthma were selected by using the Global Initiative for Asthma guidelines and were randomly divided into the study (group I) (n = 36) and control (group II) (n = 22) groups. Mycoplasma pneumonia-specific immunoglobulin G and -specific immunoglobulin M antibody levels of each participant were measured by enzyme-linked immunosorbent assay. Clarithromycin 5 mg/kg daily and placebo were given to groups I and II, respectively, for 4 weeks. All of the children had maintenance inhaled corticosteroid (fluticasone propionate, one puff twice [50 fig/puff] daily). Forced expiratory volume in 1 second, forced expiratory flow at 25–75% of the pulmonary volume, exhaled nitric oxide value, total IgE level, absolute eosinophil count, and eosinophilic cation protein value were measured at baseline and at the end of the treatment. Results There are significantly increased forced expiratory volume in 1 second and forced expiratory flow at 25–75% of the pulmonary volume levels and decreased exhaled nitric oxide values after the 4-week clarithromycin treatment. The study group also had a decreased peripheral blood absolute eosinophil count and eosinophilic cation protein level, but not for the total IgE level, after the treatment. Conclusion Four weeks of sub-antimicrobial doses of clarithromycin may improve pulmonary function and decrease eosinophilic inflammation in children with asthma.

Objective: Spinal manipulation has been used to improve respiratory function in healthy individuals. However, it has been observed that there are no studies in the context of sports activities. The objective of this study was to analyse the effect of thoracic spinal manipulation on forced vital capacity, forced expiratory volume in one second and maximal voluntary ventilation in swimmers.
 Method: A randomized controlled crossover study consisting of 21 swimmers, divided into two groups (Intervention vs Control), aged 16 – 24y, where forced vital capacity, forced expiratory volume in one second and maximal voluntary ventilation were measured in five evaluation moments: at baseline and, 1 minute, 10 minutes, 20 minutes and 30 minutes following the thoracic spinal manipulation procedures.
 Results: ANOVA tests showed no statistically significant differences for forced vital capacity (p = 0.35) and forced expiratory volume in one second (p = 0.25) among the five evaluation moments. With the maximal voluntary ventilation there was a statistically significant (p = 0.02) reduction, observed between baseline (86.00 litres) and at 10 minutes (79.29 litres) and 30 minutes (76.24 litres). No significant differences were observed between the results of intervention and control groups.
 Conclusions: In the current study no significant differences were observed in pulmonary function after thoracic spinal manipulation. Future research efforts should examine the effects of different manual therapy techniques and treatment protocols.

Full textAbstract:
Ventilatory pulmonary function was investigated in 160 children and adults with repaired or unrepaired congenital cleft palate in comparison with 130 normal children and adults. Pulmonary function tests included measurement of lung volumes, of maximal voluntary ventilation (MVV) and of forced spirometry parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio and mean forced expiratory flow during the middle half of FVC (FEF25–75). Patients with cleft palate demonstrated significant differences from normal individuals in some of the measurements made. Functional alterations were observed at higher frequency among adult patients with unrepaired clefts and mainly consisted of a reduction in expiratory flows and MVV. However, the deviations observed were usually discrete and probably of low Physiopathologic significance. The results permit us to conclude that, in contrast to data reported by others, subjects with congenital cleft palate have little impairment of pulmonary ventilatory function.

BACKGROUND: Pulmonary function is a main factor influencing postoperative morbidity and mortality in thoracic surgery. OBJECTIVE: To determine the significance of surgical trauma on postoperative pulmonary function by comparing the preoperative forced expiratory volume in 1 second with that obtained 14 days after surgery. METHODS: A retrospective study was conducted on 385 consecutive patients undergoing elective thoracic surgery over 3 years. RESULTS: Operative trauma alone effected a reduction of approximately 0.6 L per second in the value of forced expiratory volume in 1 second irrespective of the extent of pulmonary resection. Significant differences in the overall reduction among enucleation, segmental resection, lobectomy, and pneumonectomy were not observed. CONCLUSIONS: The data indicated that the remaining lung tissue was severely compromised throughout the postoperative period and that surgical trauma was the main factor influencing postoperative pulmonary function for at least 2 weeks.

Background: This study aims to systematically examine the cardiopulmonary functions in children with pectus excavatum and to compare the obtained findings with the Haller Index. Methods: Between September 2017 and June 2018, medical records of a total of 31 patients (27 males, 4 females; mean age: 14.8±2.0 years; range, 9 to 18 years) with pectus excavatum were retrospectively analyzed. The patients were divided into Group 1 (<2.5), Group 2 (2.5 to 3.19), and Group 3 (>3.2) according to the Haller Index. All groups were systematically evaluated based on pulmonary function tests and echocardiography. Forced vital capacity, forced expiratory volume in 1 second, and the forced expiratory volume in 1 second/ forced vital capacity ratio were calculated. Left ventricular enddiastolic diameter, ejection fraction, mitral valve prolapses, and right ventricular cavity in the apical four-chamber position were evaluated with echocardiography. Results: Of the patients, 19.4% were in Group 1, 38.7% in Group 2, and 41.9% in Group 3. The mean Haller Index value was 3.09±0.64. According to pulmonary function test results, 16.1% of the patients had restrictive disease and 6.5% had obstructive disease. There was a negative correlation between the index and forced expiratory volume in 1 second and forced vital capacity, and there was a statistically significant decrease in these values, as the Haller Index increased (p<0.017). There was a significant difference in the ejection fraction among the groups (p<0.001) and, as the Haller Index increased, ejection fraction statistically significantly decreased. Conclusion: Our study results show a negative correlation between the severity of pectus excavatum and pulmonary dysfunction and, as the severity increases, left ventricular function may be affected by the deformity. As a result, there seems to be a significant relationship between the severity of the deformity and cardiopulmonary functions.

In 415 nonsmoking asthmatic children who were seen consecutively, asthma symptoms were more severe if the mother was a smoker than if she was a nonsmoker. This applied to both sexes but was more marked in boys than in girls. There were also other indications that sons were the more severely affected: the forced expiratory volume at 1 second, the forced expiratory flow rate during the middle half of the forced vital capacity, and the provocation concentration of histamine needed to result in a 20% decrease in the forced expiratory volume at 1 second were significantly decreased only in the sons, and lung function test results were significantly less in sons than in daughters of mothers who smoked. When the 415 children were stratified according to age, lung function improved significantly with increasing age in the children of nonsmokers; in children of smokers, by contrast, symptoms and lung function test results became progressively worse. As well, there was a correlation between these indications of asthma severity and the number of years the child had been exposed to the mother's smoke. It appeared that, compared with girls, boys were more sensitive to passive smoking, and that its adverse effect increased with age and with duration of exposure.

Background/Aims The number of studies exploring isolated upper extremity muscle strength and endurance in paediatric patients with cystic fibrosis is limited. The aim of this study was to investigate the relationship between upper extremity muscle strength and endurance with respiratory functions, functional capacity and quality of life in children and adolescents with cystic fibrosis. Methods Children and adolescents with cystic fibrosis performed a flexed arm hang test to measure muscle endurance, movement against a dynamometer to measure muscle strength, a pulmonary function test and 6-minute walk test to measure functional capacity. The Cystic Fibrosis Questionnaire Revised was used to assess quality of life. Results A total of 29 children and adolescents with cystic fibrosis (15 girls, 14 boys) participated in the study. Biceps muscle strength moderately correlated with forced expiratory volume in 1 second predicted percentage, forced vital capacity predicted percentage and the ratio of forced expiratory volume in 1 second to forced vital capacity predicted percentage (r=0.306, P=0.035; r=0.405; P=0.029; r=0.367, P=0.048, respectively). Biceps muscle strength, shoulder abductors muscle strength, hand grip strength and flexed arm hang test correlated with the ratio of forced expiratory volume in 1 second to forced vital capacity predicted percentage. Biceps muscle strength, shoulder abductors muscle strength, hand grip strength and flexed arm hang test correlated with 6-minute walk test distance (r=0.678, p<0.001; r=0.732, p<0.001; r=0.512, P=0.005; r=0.375, P=0.045, respectively). Biceps muscle strength and shoulder abductors muscle strength moderately correlated with emotional functioning and eating disturbances in the Cystic Fibrosis Questionnaire Revised (r=0.451, P=0.014). Conclusions Specific assessment of upper extremity muscle strength and endurance in children and adolescents with cystic fibrosis may be helpful in informing physiotherapists of respiratory function, functional capacity and quality of life status.]

Full textAbstract:
Background: Spirometry is an unrivalled tool for determining asthma and asthma severity. The ratio of forced expiratory volume (FEV) in 1 second (FEV1) to forced vital capacity (FVC) and the forced expiratory flow between 25% and 75% of FVC (FEF25-75) are well-known markers of airway obstruction, but they are limited by low reproducibility, particularly in children. In this study, we defined terminal expiration volume (TEV) as FEV in 3 seconds forced expiratory volume in 3 seconds (FEV3) minus forced expiratory volume in 1 seconds (FEV1) and investigate whether TEV/FEV3 can function as a coherent marker to compensate for existing markers. Methods: This retrospective study comprised 980 children ages ≤ 18 years who underwent spirometry and the bronchial provocation testing. TEV/FEV3 was compared with regard to asthma presence and severity. The findings were verified with an external validation group (n = 105). Results: FEV3 was obtained in 837 children (85.4%). TEV/FEV3 was significantly higher in patients with asthma than in patients who did not have asthma (17.1 ± 5.5 versus 12.0 ± 4.4, p < 0.001). External validation with 73 patients showed similar results (18.0 ± 5.9 in asthma versus 10.2 ± 5.1 in non-asthma, p < 0.001). The discriminatory power of TEV/FEV3 for asthma was comparable with that of FEF25-75 (p = 0.804). TEV/FEV3 significantly increased with asthma severity (mild, 16.1 ± 5.4; moderate, 17.7 ± 5.4; severe, 22.0 ± 5.3; p < 0.001). For patients who could not achieve FEV3, FEF25-75 demonstrated no significant difference between mild and moderate asthma, and could not discriminate asthma or asthma severity. Conclusion: TEV/FEV3 is a new metric that may help diagnose and determine asthma severity by using conventional spirometry by assessing small airway dysfunction. TEV/FEV3 promotes a reassessment of the reliability of other spirometric parameters, particularly in young children. Caution is needed in interpreting the result of spirometry in children who cannot achieve FEV3.

Obesity and pulmonary diseases are said to be co-prevalent and debilitating chronic illnesses that are becoming more and more commonplace globally. This study thus, evaluated the changes in basic pulmonary indices of obese women resident in Rivers State, Nigeria. The minimum sample size of 272 was determined using the Leslie Fischer's formula; exactly 334 obese and non-obese women within their 18 and 65 years of age with no critical health condition and resident in Upland and Riverine areas of Rivers State were actually surveyed by the present study. A multistage sampling technique was adopted, and subjects were surveyed across the upland and riverine locations of the State. These subjects were evenly drawn from the multi-ethnic residents of the state. Automated spirometer was used to measure forced vital capacity (FVC); forced expiratory volume in 1 second (FEV1 and forced expiratory volume in 1 second (FEV1) and forced expiratory volume in 6 second (FEV6) and the FEV1/FVC ratio. The quantitative data were subjected to statistical analyses using the statistical package for social sciences (SPSS) version 21.0. One-way analysis of variance (ANOVA) and independent t-test with a p< 0.05 considered statistically significant were determined. The result indicated that the obese subjects had reductions in some pulmonary indices, like FVC levels. On the other hand, the FVC/ FEV1 ratio had significant (p<0.05) increases following increasing BMI. Further evaluations on the actual impact of obesity on FVC/ FEV1 ratio may shade more light in this direction.

Fasting in the month of Ramadan is an obligatory duty for muslims. Researchers have investigated health benefits of fasting and reported conflicting results. The purpose of this study was to determine the immediate and delayed effects of Ramadan fasting on spirometric parameters. 50 apparently healthy young adults aged between 17-27 years, belonging to both genders who fast during the month of Ramadan were enrolled for the study. Spirometric recordings were done at three different time points. First: 5-10 days before the start of Ramadan (Pre-Ramadan); second: within 10 days of the beginning of Ramadan fasting (Ramadan); third: within 7 days of the end of Ramadan (Post-Ramadan). There were no statistically significant differences between the three phases with respect to tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), FEV1/FVC, peak expiratory flow rate (PEFR) and forced expiratory flow 25% to 75% (FEF25-27). To conclude, Ramadan fasting does not have any significant effect on pulmonary function tests as assessed by spirometry. Hence, the diagnosis and prognosis of a respiratory disorder made on spirometry findings are reliable and need no error correction if an individual is fasting.

Abstract Background Neuromuscular diseases are acquired or inherited diseases that affect the function of the muscles in our body, including respiratory muscles. Objective We aimed to discover more cost-effective and practical tools to predict respiratory function status, which causes serious problems with patients with neuromuscular disease. Methods The Vignos and Brooke Upper Extremity Functional Scales were used to evaluate functional status for patient recruitment. The handgrip strength and dexterity of patients were measured using a dynamometer and nine-hole peg test. Respiratory function parameters: forced vital capacity, forced expiratory volume in one second, and peak expiratory flow were evaluated using spirometry. Results The mean age of the 30 patients was 11.5 ± 3.79 years old. Significant relationships were found between nine-hole-peg-test scores and respiratory function parameters on both sides. Significant correlations were found between both handgrip strength and respiratory function parameters (p < 0.05). In the linear regression analysis, it was seen that the forced expiratory volume in 1 second, and peak expiratory flow values could be explained in different percentages (p < 0.05). Conclusions Handgrip strength and dexterity measurements can be used as indicators for estimating respiratory function parameters in terms of cost and accessibility, although it is known that they will not replace respiratory function tests.

Background and Aims- The six minute walk test is widely used as an outcome measure in pulmonary rehabilitation programs. The objective of this study is to report the magnitude of change in the six minute walk test with test repetition in patients with chronic obstructive pulmonary disease on pulmonary rehabilitation program. Methods: A prospective study of 51 patients with moderate to very severe COPD was carried out. Clinical examination, spirometry, six minute walk distance were done. All were advised regular follow up visits at three, six and twelve months. Results: Four (8%) very severe cases completed all visits and one in those showed improvement in Forced Expiratory Volume in 1 second by 6% and six minute walk distance by 71 metres. Seven (31.37%) severe cases completed all visits; showed improvement in Forced Expiratory Volume in 1 second by 2.5%; the distance walked was a mean 381.5 metres and this was 2.5 % improvement over base line walking distance. Six (11%) moderately severe cases completed the study; the mean distance walked at the end of the study was 451 metres, which is an improvement of 53% and the mean change in Forced expiratory volume in 1 second was <2%. Totally, the mean of modified Burden of Lung disease Dyspnoea scale was 1.7 (baseline) and 4 (after the test). Conclusions: These findings support the recommendation of practice six minute walk test at baseline assessment in order to provide an accurate measure of the effects of rehabilitation on six minute walk distance.DOI: http://dx.doi.org/10.3126/jaim.v2i2.8774 Journal of Advances in Internal Medicine 2013;02(02):35-41.

<strong>Background:</strong> Pregnancy involves the maternal body’s adaptation to meet the increasing physiological demands of a developing fetus. This process induces numerous visible and subtle changes in the body, and it is one of the prime examples of selective adaptation within respiratory physiology. The objective of this study is to evaluate and compare specific pulmonary function parameters, particularly forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), between healthy pregnant and healthy non-pregnant women. <strong>Materials and Methods:</strong> A total of 492 women were categorized into four groups (123 each): non-pregnant women and pregnant women in their 1st, 2nd, and 3rd trimesters. The inclusion criteria were women aged 20-30 years, without systemic illnesses affecting pulmonary function, capable of performing pulmonary function tests. Exclusion criteria were individuals with a history of respiratory disorders, healthy women with a history of substance use, and prior history of lung disease. Pulmonary function assessments were performed using computerized spirometry. <strong>Results:</strong> A statistically significant reduction in FEV1 and FVC was observed across all three trimesters in the pregnant cohort compared to the non-pregnant group. The study indicates a marked increase in weight during pregnancy, particularly in the second and third trimesters, along with a significant decline in pulmonary function, as reflected by reduced FEV1 and FVC values as pregnancy progresses. <strong>Conclusion:</strong> FEV1 and FVC were notably reduced throughout pregnancy. These changes are likely attributed to the mechanical influence of the expanding uterus and the hormonal effects of estrogen and progesterone on respiratory physiology in pregnant women.

Aim:The aim of this study is to examine the effects of smoking addiction and physical activity on some of the respiratory functions in female university students. Methods:103 female students who did not have any health problems, who had an average age of 20,00 (years), average height of 163,6 (cm) and average weight of 55,88 (kg) participated in the study voluntarily. Female students who participated in the study were grouped according to their states of having smoking addiction (athlete, sedentary) and doing exercise (athlete, sedentary) and later some of the respiratory functions were measured. SPSS program was used in the statistical analysis of the data obtained. Shapiro-wilk test was used to find out the normality distribution of the data. Kruskal Wallis test was used in the analysis of the data which were not normally distributed and Mann-Whitney U test was used in sub-groups. Results: FVC(Forced Vital Capasity), FEV1(Forced Expiratory Volume in 1 second), FEV1(Forced Expiratory Volume in 1 second )/FVC(Forced Vital Capasity), PEF(Peak Expiratory Flow), FEF25-75% (Forced Expiratory Flow at 25-75% ), VC(Vital Capacity) and MVV(Maximal Voluntary Ventilation) values of the female students who were engaged in sports were found to be significantly higher when compared with the groups which were not engaged in sports (p<0,05). Conclusion:In addition, in terms of the variable of smoking addiction, statistically significant difference was found between the FEV1, FEV1/FVC(%), PEF (L/s), FEF25-75% (L/s) and MVV values of the female student groups in favour of sedentary and athlete students who were not smokers.

Abstract Background: Sickle cell anemia (SCA) is a life threatening monogenic disorder associated with early death. Platt et al. reported median ages of death (42 years males; 48 years females) from the Cooperative Study of Sickle Cell Disease (CSSCD). Forced expiratory volume in one second (FEV1) on pulmonary function testing (PFT), is commonly used to monitor disease severity in individuals with asthma, cystic fibrosis (CF) and chronic obstructive pulmonary disease. FEV1 (% predicted) has been shown to predict mortality in the general population, but no PFT result has predicted earlier death in SCA. We tested the hypothesis that abnormal pulmonary function was associated with earlier death. Methods: A prospective cohort study using the CSSCD data was constructed. We evaluated a total of 430 participants from the CSSCD study who had evaluable PFT, using data from the first PFT at age 21 years and older, and reviewed centrally for quality. Predicted values were determined for each subject based on age, gender, height, and race for FEV1, forced vital capacity (FVC), and the FEV1/FVC ratio using the Global Lung Function 2012 equations. Abnormal results for FEV1, FEV1/FVC, and FVC were determined by comparison to their lower limits of normal. Predicted values for total lung capacity (TLC) were obtained utilizing the prediction equations published, and adjusted by 12% to account for the effect of race on these values; a value <80% predicted was considered abnormal. Values of FEV1, FEV1/FVC, FVC, and TLC were used to categorize PFT patterns as normal, obstructive, or restrictive based on American Thoracic Society/European Respiratory Society guidelines according to a modified algorithm based on Pellegrino (2005). Assessment of the association between PFT and mortality was investigated using Kaplan-Meier product limit estimation and Cox proportional hazards regression. The full regression models were adjusted for factors known to be associated with mortality. Multivariable Cox regression models were constructed, and only covariates that were nominally significant predictors (p<0.20) were used for the final model. FEV1% was reverse-coded so that lower values are associated with hazard ratios above 1. Results: Median age was 31.4 years at time of first PFT and median follow-up was 5.5 years. In the cohort, 47% had normal, 29% restrictive, 8% obstructive, 2% mixed, and 14% non-specific pulmonary function patterns. There were no differences in SCA severity between groups (PFT vs no PFT). During follow-up, 63 (15%) participants died. Those who died had significantly higher WBC, lower hemoglobin levels, and lower FEV1% predicted, but not lower FEV1/FVC ratio. Pulmonary function patterns were not associated with earlier death- obstructive (p= 0.97), restrictive (p=0.41), and non-specific (p= 0.609). In the final multi-variable model, lower FEV1% predicted is associated with increased hazard of death [HR per %-predicted 1.02 (95% CI 1.00 – 1.04; p =0.037)], as did older age [HR 1.07 (95% CI 1.04-1.10; p<0.001)], male sex [HR 2.09 (95% CI 1.20-3.65; p=0.010)], higher ACS incidence rate [HR per event/yr 10.4 (95% CI 3.11-34.8; p <0.001)], LDH [HR per mg/dl 1.002 (95% CI 1.00-1.003; p = 0.015)] Table. A threshold of <70 FEV1 % predicted was associated with earlier death (Log rank test (p =0.002) Figure. Conclusion: For the first time, we have demonstrated that spirometry evaluation with FEV1% predicted identifies adults with sickle cell anemia who have increased hazard of death. Routine spirometry testing should become standard care in individuals with SCA, enabling early intervention for those at risk.

Background Asthma is the most common chronic disease in the world, with a high incidence in children. Blood gas analysis and pulmonary function test using spirometry are recommended to evaluate the degree of asthma in children. Spirometry test is non-invasive and easier to implement compared to blood gas analysis.
 Objective To evaluate for a possible correlation between forced expiratory volume in 1 second (FEV1) measured by spirometry test and blood gas analysis (pO2 and pCO2 levels) in children during an asthma attack.
 Methods This cross-sectional study was done in children with asthma attacks who were admitted to Sanglah Hospital, Denpasar, Bali, between November 2016 and April 2017. Subjects underwent spirometry tests and blood gas analyses. Potential correlations between FEV1 and pO2 and pCO2 levels were analyzed by Spearman’s correlation test.
 Results A total of 50 subjects, consisting of children aged 6 to 12 years, were diagnosed with asthma attacks during the study period. Subjects’ mean FEV1 level was 43.6%, mean pCO2 was 38.36 mmHg, and mean pO2 was 121.92 mmHg. There were no significant correlations between FEV1 and pCO2 level (r=0.206; P=0.152) or FEV1 and pO2 (r=0.157; P=0.277) found in this study.
 Conclusion FEV1 does not correlate with pCO2 and pO2 level in children during asthma attacks.
