The European Resuscitation Council (ERC), the American Heart Asso

The European Resuscitation Council (ERC), the American Heart Association (AHA) and other international emergency medical organisations published their guidelines for cardiopulmonary resuscitation in 2005 and 2010 [1,8-10]. As a reasonable compromise between maximised periods of uninterrupted ECC, interposed ventilations and rescuer fatigue the recommended compression-ventilation ratio (CVR) for adults was changed Inhibitors,research,lifescience,medical from 15:2 to 30:2 in 2005 [4]. Subsequent studies comparing the two CVRs gave conflicting results. While participants of one study claimed 30:2 to be more exhausting, other

investigators found that the quality of ECC did not decrease with the 30:2 ratio during a 10-minute, single-rescuer scenario [11,12]. The aim of this prospective, randomised, manikin-based, Inhibitors,research,lifescience,medical cross-over study was to investigate the inhibitor Bosutinib impact

of the rescuers’ physical fitness, biometry and gender on the quality of ECC using CVRs of 15:2 and 30:2. Furthermore, we aimed to determine objective parameters of physical fitness that reliably predict the quality of ECC. Methods Study participants After obtaining the approval of the Ethics Committee of the Medical Faculty of the Georg-August-University, Göttingen, we recruited, prior to the publication of the updated guidelines for cardiopulmonary resuscitation in 2010, 30 male and 10 female volunteers with written informed consent from Inhibitors,research,lifescience,medical the Göttingen Fire Department (paramedics) and the Göttingen University Hospital (intensive-care nurses and physicians) to this exploratory study. All participants were competent in Basic Life Support (BLS) Inhibitors,research,lifescience,medical and certified Advanced Life Support (ALS) providers. No

participant was taking cardiovascular or respiratory medications, had recently underone a surgical intervention, had suffered any cardiopulmonary disease or had any other cause of limited physical endurance. Part I: Physical fitness test The physical fitness of all Inhibitors,research,lifescience,medical participants was evaluated by two different consecutively performed ergometric endurance tests two days before the ECC trials. First, a cycle ergometry (ERG 551, Bosch, Stuttgart, Germany) test was used following a protocol with a stepwise increase of physical strain every three minutes that started Brefeldin_A at 50 watts and was increased by 50-watt steps up to a minimum strain of 150 watts. If the participant’s heart rate (HR) did not reach 100 beats per minute (bpm) at the end of the 150-watt step, a fourth step of 200 watts was added. Depending on the HR at the 50 – 150 – (or 200-) watt steps, a final maximum step was individually defined in order to reach a HR of 170 bpm. The pedal rate had to be kept constant at 50-60 revolutions/min. The workload required to reach a HR of 170 was determined as the personal watt capacity (PWC170), which represents a validated standard parameter for physical fitness in sport physiological investigations [13,14].

At this point in time, the identification of the “I” score may not be very precise. The introduction

of the “I” score might prove more useful when a precise method for the identification of instability is identified. However, clinical acute coronary events can always be deemed the highest “I” score. This equation can be used in prospective studies on the association between traditional and novel risk factors and atherosclerosis velocity. A summary Inhibitors,research,lifescience,medical of the description and application of atherosclerosis velocity can be observed in figure 2. Importance of Atherosclerosis Velocity We believe that in several previous investigations, atherosclerosis velocity has not been sufficiently studied. In other words, as much as we currently know various parameters believed to be the causative or consequence factors of atherosclerosis, we really do not have a good understanding of the effects of these factors on atherosclerosis velocity. Saremi et al.17 reported that Pioglitazone, a drug of the HKI-272 mouse Thiazolidinedione class with hypoglycemic action to Inhibitors,research,lifescience,medical treat diabetes, slowed the progression of carotid intima media thickness (IMT) during an average follow-up of 2.3 years compared to placebo. Inhibitors,research,lifescience,medical Imagine if another study examines compound X in a matched group of patients and reaches the same curve of IMT decrease but in one year; it would mean that compound X could decrease atherosclerosis velocity almost by 50%. Another example

Inhibitors,research,lifescience,medical in this regard is the study of Yamazaki et al.18 They showed that in patients under statin therapy at a 12-month measurement point, mean-IMT change was correlated with LDL-C and LDL-C/ HDL-C. Sun et al.19

recently performed an interesting study which almost combined all three parameters of time/ duration, plaque volume, and plaque vulnerability/instability characteristics. The authors characterized the impact of atherosclerosis on the short-term (6 months) natural history of the lipid-rich Inhibitors,research,lifescience,medical necrotic core (LRNC) in carotid artery plaques using MRI and concluded that LRNC was essentially affected by the characteristics of plaque stability, which seemed to be even more important than clinical features. Several previous articles have concluded that atherosclerosis is a chronic disease.4,5 However, we think that it is time we considered the term “acute atherosclerosis”. selleck inhibitor Acute atherosclerosis represents a rupture-induced occlusion and is a disorder that may develop even a very short time after plaque formation. Atherosclerosis velocity has dependency on plaque stabilization and acute rupture. Therefore, if we assume that the endpoint of atherosclerosis is acute coronary occlusion and/or gradual arterial narrowing-induced ischemia, we should then turn our attention to the risk factors that contribute to a rise in atherosclerosis velocity. Inflammation is known to be a crucial component of atherosclerosis10,20,21 and plays an important role in plaque instability.

Rawson et al. reported the first demonstration of a direct interface of vertically aligned SWCNTs (VASWCNTs) with eukaryotic RAW 264.7 mouse macrophage cell line. VASWCNTs entered the cells naturally due to its needle-like structure without application of any external force owing to selleck screening library endocytosis independent pathway for internalization [114]. 5. Application of CNTs in Cancer Treatment For

decades, human immortal cancer cell lines Inhibitors,research,lifescience,medical have constituted an accessible, easily usable set of biological models with which to investigate cancer biology and to explore the potential efficacy of anticancer drugs is of less tedious work. Currently, various ex vivo studies, such as cell line studies, cellular uptake studies, fluorescent microscopy, and flow cytometry, are carried out for this purpose. Various cancer cell lines were cultured with modified CNTs (functionalization on the surface and ends of the CNTs, and by conjugating CNTs with ligands) and evaluated for therapeutic

Inhibitors,research,lifescience,medical efficacy, cell viability, cell survival assays, and cell apoptosis. Ex vivo studies specifically used in the evaluation of CNTs for cancer chemotherapy are shown in Table 1. Table 1 Impact of functionalized CNTs on cancer cell lines. 5.1. Brain Cancer Brain cancer is the leading cause Inhibitors,research,lifescience,medical of cancer-related death in the US in patients Inhibitors,research,lifescience,medical under the age of 35. Anaplastic astrocytomas (Grade III) and glioblastomas (Grade IV) are most aggressive brain cancers with survival period of 24 and 9 months, respectively [138]. Children who survive their brain cancers (mainly medulloblastomas)

often suffer substantial adverse effects related to the toxicities of therapy on the developing nervous system [139]. Currently available systemic chemotherapy is less effective due to presence of the blood-brain barrier (BBB) Inhibitors,research,lifescience,medical which restricts the penetration of most drugs into the brain. Recently, a number of CNT-based targeting approaches have been developed for the treatment of brain cancer and a brief account PLK inhibitor is presented below. Vittorio et al. investigated the biocompatibility of MWCNTs with cultured Human neuroblastoma cells SH-SY5Y. Reactive oxygen species (ROS) are chemically reactive molecules containing oxygen. ROS can damage cellular proteins, lipids, and DNA leading to fatal lesions in cells that contribute to carcinogenesis. In vitro experiments showed loss of cell viability was minimal with no intracellular ROS detected with prolonged cultures and continued propagation in the presence of 99%, 97% pure MWCNTs and acid-treated 97% pure MWCNTs but no significant decrease in the proliferation of cells incubated for 3 days was observed with the cells cultured with 99% pure MWCNTs.

​(Fig.1).1). During submaximal exercise of moderate

intensity (< 50% vO2max), muscle initially utilizes blood glucose, but – as the exercise continues beyond a few hours – there is a gradual shift from the oxidation of glucose, a finite fuel derived from liver glycogen, to the oxidation of fatty acids, a virtually inexhaustible fuel derived from fat stores (1). Figure 1 elected metabolic pathways in a schematic rendition of a mitochondrion. The spirals indicate the sequential reactions of the β-oxidation pathway, resulting in the liberation of acetyl-coenzyme A (CoA) and the Inhibitors,research,lifescience,medical reduction of flavoprotein. Abbreviations: ... Two reactions are immediate sources of energy: (i) the creatine kinase (CK) reaction that breaks phosphocreatine Inhibitors,research,lifescience,medical (PCr) down to ATP and creatine in the presence of ADP through the creatine kinase (CK) reaction (PCr + ADP + H+ = ATP + Cr); and (ii) the adenylate kinase reaction, generating ATP and AMP from the condensation of two molecules of ADP (2ADP = ATP + AMP). However, by far the largest amount of energy for exercise derives from Inhibitors,research,lifescience,medical oxidative phosphorylation in the mitochondria and a much smaller amount of energy comes from anaerobic glycolysis, which is crucial only during isometric contraction (when blood supply is virtually cut off). The still widely

held belief that the exercise Inhibitors,research,lifescience,medical intolerance that characterizes many glycogenoses is due to a block of anaerobic glycolysis is exaggerated and probably due to the popularity of the forearm ischemic exercise introduced by Brian McArdle in 1951 (2). In truth, the pathophysiology of exercise intolerance in McArdle Inhibitors,research,lifescience,medical disease and similar muscle glycogenoses is mostly due

to a block of aerobic glycolysis. Disorders of energy supply to muscle, irrespective of whether the defects involve carbohydrate metabolism, lipid metabolism, or the respiratory chain, result in one of two syndromes: (i) exercise intolerance, often punctuated by recurrent and reversible “crises” of muscle breakdown (rhabdomyolysis) Brefeldin_A and myoglobinuria; or (ii) chronic subacute weakness (Fig. ​(Fig.2).2). Focusing our attention on the glycogenoses, all defects associated with the former syndrome involve glycogen breakdown or glycolysis and are triggered by exercise, whereas the latter syndrome is associated with defects in a glycogen synthetic enzyme (brancher), the lysosomal glycogenolytic enzyme (acid maltase [α-glucosidase]), one glycolytic enzyme (aldolase), and, rather surprisingly, a glycogenolytic enzyme (debrancher) that works hand-in-hand with myophosphorylase The pathogenesis of weakness in the second group of glycogenoses is not completely clear. In part, at least, it Ruxolitinib 941678-49-5 relates to the multisystem nature of the enzyme defects.

23 Perfusion measured with ABI and TcPO2 at baseline and after 6 months increased in patients with consecutive limb salvage (ABI 0.33±0.18 to 0.46±0.15, TcPO2 12±12 mmHg to 25±15 mmHg) but did not change in patients eventually undergoing major amputation. Clinically most important, patients who did not require amputation saw an improvement in mean Rutherford category from a baseline of 4.9 to 3.3 at 6 months (P = 0.0001). Furthermore, analgesics consumption

was reduced by 62%.23 In BONMOT-1 and the subsequent placebo-controlled, double-blind study (BONMOT-CLI), BM-MNC injections were placed along the axial Inhibitors,research,lifescience,medical line of the occluded native arteries; this maximizes efficacy because the density of preformed collaterals is highest in parallel orientation to the axial arteries, which is the location for collateral growth. In BONMOT-1 and BONMOT-CLI, the number of injections was also increased corresponding to the length of the arterial occlusion, from 40 injections for infra-popliteal disease only to 60 injections when femoral, popliteal, Inhibitors,research,lifescience,medical and infra-popliteal disease was present. In the RESTORE–CLI trial of 77 patients, Ixmyelocel-T treatment led to a significantly prolonged first occurrence of treatment failure (e.g., major amputation of injected leg, all-cause mortality, Inhibitors,research,lifescience,medical doubling of total wound surface area from baseline, de novo gangrene) (P = 0.0032, logrank test). Amputation-free

survival (major amputation of injected leg; all-cause mortality) saw a 32% reduction, but this was not statistically significant (P = 0.3). Treatment

effect in post hoc analyses of patients with baseline wounds was more pronounced.24 In the interim Inhibitors,research,lifescience,medical analysis of the HARVEST trial, the BMAC (bone marrow aspirate concentrate) group demonstrated trends toward improvement in amputation, pain, quality of life, Rutherford classification, and ABI when compared with controls.25 INTRA-ARTERIAL BM-MNC: In the Inhibitors,research,lifescience,medical PROVASA (Intra-arterial Progenitor Cell Transplantation of Bone Marrow Mononuclear Cells for Induction of Neovascularization in Patients With Peripheral Arterial Occlusive Disease) study, 40 patients were randomized to intra-arterial delivery of either BM-MNC or placebo.26 There was a significant improvement in VX-680 price ulcer healing and significant rest pain reduction in subjects treated with BM-MNC versus placebo. The trial also demonstrated that multiple treatments of BM-MNC were associated with significantly greater improvements in ulcer healing and rest pain than a single treatment. However, patients with Rutherford class ischemia (Sunitinib cell line gangrene or major tissue loss) at baseline did not respond to therapy. The major predictors of successful ulcer healing were total cell number delivered, repeated cell administration, and greater cell functionality measured by in vitro assays. INTRA-ARTERIAL AND INTRAMUSCULAR BM-MNC: Combined intra-arterial (IA) plus intramuscular (IM) BMC delivery may be more effective than exclusive intramuscular injections.

The need of Inhibitors,research,lifescience,medical children for palliative care is well recognised [1-9] but difficult to define. It is defined by the needs of an individual child and family when cure is no longer possible, rather than by age or organ system. The Royal College of Paediatrics and Child Inhibitors,research,lifescience,medical Health (RCPCH),

working with the Association for Children’s Palliative Care (ACT) in 1997, defined the concept of life-limiting condition [6] through a series of archetype descriptions (Table 1), but did not attempt to name specific diagnoses except as exemplars. If, however, children are to have the same access to specialist palliative interventions as adults currently enjoy, service developers must engage commissioners. That requires a precise understanding Cilengitide of the numbers of children who need services, which in turn requires specific diagnostic criteria. Table 1 ACT/RCPCH Categories[6] We developed a Directory of life-limiting conditions by mapping the four ACT/RCPCH archetypes onto the diagnoses of actual patients admitted to hospice or palliative care services in the UK. We then piloted the Directory by using it to interrogate death certificate data for children in Wales over a five-year period. We describe development of the Directory and, in the light of results of the pilot study, consider some of its current limitations as well as the wider applications in taking forward service and research developments in children’s palliative care.

61 While problematic gambling behavior has been recognized for centuries, it was often ignored by the psychiatric community. Bleuler,17 citing Kraepelin,16 considered PG, or “gambling mania,”

a special impulse disorder. Criteria for PG were first enumerated in 1980 in DSM-III. 62 The criteria were subsequently modified, and in DSM-IV-TR, 10 are patterned after those used for substance dependencies and emphasize the features of tolerance and withdrawal. PG is defined as “persistent and recurrent maladaptive gambling behavior (criterion A) that disrupts personal, Inhibitors,research,lifescience,medical family, or vocational pursuits…” Ten specific maladaptive behaviors are listed, and >5 are required for the diagnosis. The criteria focus on loss of control of gambling behavior; progressive deterioration of the disorder; and continuation despite negative consequences. The diagnosis can only be made when mania is ruled out (Criterion B). In an attempt to reconcile nomenclature and measurement methods, Shaffer and Hall63 developed a generic multilevel Inhibitors,research,lifescience,medical classification scheme that is now widely accepted by gambling researchers. PG is presently classified as a disorder of impulse control in DSM-IV-TR. 10 On the one hand, some

investigators have suggested that PG is related to OCD,1,64 yet others argue against such a relationship.65 Inhibitors,research,lifescience,medical On the other hand, PG is widely considered an addictive disorder.66,67 It has recently been proposed as a candidate for inclusion in a new category for “behavioral addictions.” 15 Recent estimates of lifetime prevalence Inhibitors,research,lifescience,medical for PG range from 1.2% to 3.4% in the general population.68,69 Prevalence rates have risen in areas where gambling availability has increased.70.71 A national survey showed that the availability of a casino within 50 miles is associated with a nearly twofold increase in PG prevalence.59 Gambling behavior typically begins in adolescence,

with PG developing by the late 20s or early 30s,72 though it can begin Inhibitors,research,lifescience,medical at any age through senescence. Rates of PG are higher in men, but the gender gap may be narrowing.PG has a later onset in women yet progresses more rapidly (“telescoping”) than in men,73 at a rate similar to that observed in alcohol disorders. Populations at risk include adults with mental health or substance-use disorders, persons who have been incarcerated, African-Americans, and persons with low socioeconomic status.74,75 Research has not validated PG subtypes, but perhaps the most widely discussed distinction is between “escape-seekers” and “sensation-seekers.” Brefeldin_A 76 lifescience escape-seekers are often older persons who gamble out of boredom, from depression, or to fill time, and choose passive forms of gambling such as slot machines. Sensation-seekers tend to be younger, and prefer the excitement of card games or table games that involve active input.76 Blaszczynski and Nower77 have proposed a “pathways” model that integrates biological, developmental, cognitive, and other determinants of disordered gambling.

King Faisal Specialist Hospital & Research Center is a major tert

King Faisal Specialist Hospital & Research Center is a major tertiary care institution, serving patients referred throughout the Kingdom of Saudi Arabia and Middle East, and hence, the expectations of these patients are very high. The ED is an important entry point to the health care system in the institution. The ED is a 30 bed unit based within an 800 bed tertiary care center. The ED serves all critical patients and those patients

followed up at the various sub-specialty departments. It has an annual volume of 65,000 patients, with 73% of them being above 14 years of age. A large percentage of the patients are followed up for tertiary care problems in several specialties, such as oncology including bone marrow Inhibitors,research,lifescience,medical transplant, cardiovascular diseases, neurosciences, medical genetics, and renal and liver transplants. Since the hospital functions as a highly specialized central tertiary care center for the country, the patient mix is quite different than other general hospitals. Our hospital receives patients Inhibitors,research,lifescience,medical with tertiary care needs from a large geographic area, as these individuals do not have access to tertiary care elsewhere in the country. Prolonged waiting before Inhibitors,research,lifescience,medical treatment in the ED may negatively color patients’ perceptions about their care providers during such visits. The need for the use

of an objective process of patient prioritization, and the theoretical applicability of the CTAS to any ED, prompted us to implement the CTAS system in the institution. Inhibitors,research,lifescience,medical The CTAS has been extensively studied and validated in a variety of settings [9-11]; however, these studies were done in areas where large integrated health care systems are already established, unlike in Saudi Arabia where patients do not necessarily have an identifiable primary care provider. Additionally, our patient population has unique cultural and

linguistic features that are not present in other studies. Our study is the first in an Arab Inhibitors,research,lifescience,medical country that aims to evaluate the feasibility and validity of CTAS by comparing certain ED quality indicators with pre-established CTAS Ku-0059436 triage objectives, and to evaluate the relationship between CTAS triage level and waiting times. Methods This retrospective study was performed using randomly selected patients who presented to the Emergency Department of the King Faisal Specialist Carfilzomib Hospital and Research Center, between November 2004 and February 2005. The study was approved by the Institutional Review Board (Research Ethics Board) of King Faisal Specialist Hospital and Research Center. Data Collection A random sample of 25 charts was selected every day for the 4 month study period. The registration clerk, triage nurse and evaluating physician recorded ED patient’s arrival time, triage time and time seen by physician respectively, on the patient’s chart during his/her visit.

We matched cases to controls using important predictors of survival (age, gender, response time, presenting cardiac rhythm, bystander CPR and regional setting), and adjusted for potential confounding through conditional multiple regression techniques and adjusting for propensity score. The matching process appeared effective as there was little change in the

estimate of association when the propensity score was added to the univariable regression model. Our findings are consistent Inhibitors,research,lifescience,medical with a number of other prehospital more information studies comparing A-CPR to conventional resuscitation [10,11,16,17]. Ong et al compared manual compressions (N=499) to A-CPR compressions (N=284) in OHCA patients and found an improved rate of ROSC (34.5% v 20.2%; AOR=1.94, 95% CI 1.38-2.72), survival to hospital admission (20.9%

v 11.1%; AOR=1.88, 95% CI 1.23-2.86) and survival to hospital discharge Inhibitors,research,lifescience,medical (9.7% v 2.9%; OR=2.27, 95% CI 1.11-4.77) [10]. In a case–control study reported by Casner et al, the proportion of patients achieving sustained ROSC was also found to be greater in the A-CPR group than the C-CPR group (39% v 29%; p=0.003) [17]. This study also found that more patients presenting in asystole or agonal rhythms had a sustained ROSC with A-CPR. These findings are consistent with our study. A study by Krep et al found the AutoPulse system to an effective and safe mechanical Inhibitors,research,lifescience,medical CPR device and useful in the management of out-of-hospital cardiac arrest [18]. However, a third study did not find improvement in outcome above C-CPR. Hallstrom et al conducted a large, multicentre randomised controlled trial comparing C-CPR to A-CPR. They reported similar proportions Inhibitors,research,lifescience,medical of patients surviving to ED (C-CPR 41.3% v A-CPR 40.4%) but a lower proportion of A-CPR being discharged from hospital alive (9.9% v 5.8%; OR=0.56; P=0.06) [11]. The current European Resuscitation Council Guidelines [5] identify that clinical trials investigating the role of mechanical devices to date have been conflicting. They conclude that mechanical devices have been used effectively to support patients Inhibitors,research,lifescience,medical in special circumstances (i.e. undergoing primary coronary intervention and CT scans,

and also for prolonged resuscitation attempts) where rescuer fatigue may impair the effectiveness of manual chest compression. Whilst cautioning that the role of mechanical devices still require further evaluation, they acknowledge that mechanical devices may also have a role in the prehospital environment where Brefeldin_A extrication of patients, resuscitation in confined spaces and movement of patients on a trolley often preclude effective manual chest compressions [5]. Several studies have shown that survival from OHCA is much lower in rural areas than urban areas [12,19]. One study showed Urban patients with bystander-witnessed cardiac arrest were more likely to arrive at an emergency department with a cardiac output (odds ratio [OR], 2.92; 95% CI, 1.65–5.17; P<0.

Results: The study included 9 female and 14 male patients with an age range of 5-23 years (mean: 13.42 years). Bronchiectasis (100%) and peribronchial wall thickening (100%) were the most frequent CT abnormalities. Mucus plugging, air trapping and parenchymal involvements were respectively seen in 95.7%, 91.3% and 47.8% of patients. The overall CT score for all patients was 57.6±24.2 (means±SD). The results of pulmonary function test http://www.selleckchem.com/products/z-vad-fmk.html showed a restrictive pattern; however, in 5.3% of the patients PFT was normal. The overall Shwachman-Kulczycki score was 53.48±13.8. There was a significantly (P=0.015) negative correlation between the total CT score and Shwachman-Kulczycki score; however, there was no significant

correlation between total CT score Inhibitors,research,lifescience,medical and the results of PFT Inhibitors,research,lifescience,medical (P=0.481) Conclusion: The Brody’s scoring system for high resolution computed tomography seems to be a sensitive and efficient method to evaluate the progression of CF, and can be more reliable when we combine the CT scores with clinical parameters. Key Words: Clinical status, pulmonary function test, cystic fibrosis Introduction Cystic fibrosis (CF) is the most common fatal genetic disorder in white population.1,2 Due to new and restrict Inhibitors,research,lifescience,medical modalities in the treatment of CF patients, their survival has increased. However, CF is still responsible for major complications, which increase the mortality and morbidity rates in such

patients.3 The most common cause of mortality in CF patients is chronic pulmonary disease, which is the consequence of persistent Inhibitors,research,lifescience,medical infections and inflammations.1,2,4 To evaluate the pulmonary status in CF, a number of diagnostic procedures including chest radiography, high resolution computed tomography (HRCT), sputum culture

and pulmonary function test are considered.1,2,4-7 Since CT Scan was found to be one of the best evaluation tools for cystic fibrosis progression, CT scoring system was proposed to make the evaluation more effective.8-11 A computed tomography scoring system is a tool to describe the abnormalities found by CT scan.12 The scoring system was introduced by Bhalla and colleagues 12. Since then, a number of other scoring systems Inhibitors,research,lifescience,medical have been proposed by Helbich,13,14 Santamaria,15 and Anacetrapib Brody,16 and their colleagues. Brody’s scoring system is a lobar scoring system, which assigns a score to each lobe separately. This scoring system describes the following morphologic changes: bronchiectasis, peri-bronchial wall thickening, mucus plugging, air trapping and parenchymal involvement.16 Although different studies were conducted to show the usefulness of Brody CT scoring system in the assessment of the progression of the disease,16-19 possible correlation between the Brody scoring system and clinical status in patients with CF has not been examined. Therefore, the present study was designed to examine the correlation of the Brody scoring system with clinical parameters and pulmonary function test (PFT) in pediatric patients with CF.
