BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with a number of different comorbidities. Cardiovascular diseases (CVD) are the most frequent comorbidities in COPD. The economic burden associated with cardiovascular comorbidity (CVC) in this population of patients is considerable. The COPD patients are related to the increased systemic inflammation, reduced capacity for physical activity, and airflow obstruction. AIM: The aim of our investigation was to evaluate the dyspnea as a disabling symptom in COPD patients with cardiovascular comorbidity (CVC) especially heart failure. The main aim of this study is to evaluate its intensity in patients with COPD in stages II according to GOLD. METHODS: The investigation was conducted from December 2019 to January 2020, on pulmonology and allergology clinic and cardiology clinic of medical faculty in Skopje. We investigated 65 outpatients with COPD, 44 with different type of CVD, Group I, and 21 without CVD, Group II. All patients were with partial chronic respiratory failure (In type 1 respiratory failure hypoxemic). Patients, according GOLD initiative, were in COPD stadium II, 70% < forced expiratory volume in 1 s (FEV1)>50%. Heart condition was diagnosed on the basis of clinical examination, electrocardiography, and echocardiography of the heart. Included patients with CVD were with ejection fraction (EF) <65%. Dyspnea was measured with modified MRC (mMRC) dyspnea scale. RESULTS: The forced vital capacity and forced expiratory volume in 1 s were statically significantly higher in Group II with CVD. Dyspnea measured with Modified Medical Research Council (MRC) dyspnea scale showed statistically significantly higher values in Group I COPD patients with CVC (2.9 ± 1.4) versus Group II without CVC (1.7 ± 1.4), (p < 0.05). The perception of the higher dyspnea in Group I was associated with increased COPD assessment test-scores, in Group I: Group I (19.8 ± 9.1) versus Group II: (9.8 ± 9.1), (p < 0.001). The number of exacerbations and what is more important the number of severe exacerbation leading to hospitalizations was statistically higher in patients of Group I with CVC than in Group II without CVC (3.0 ± 1.1 vs. 1.0 ± 2.1), (p < 0.001) and the number of hospitalizations (1.0 ± 1.1 vs. 0.3 ± 2.1) (p < 0.001). CONCLUSION: We can conclude that patients with COPD who have CVC have an increased risk of high symptoms, which mean poor quality of life and increased morbidity.

Background: Airway remodeling has been shown to be persistent in patients with asthma despite treatment with controller medications. Patients with early airflow obstruction may continue to experience poor lung function despite treatment. Objectives: To determine whether early airflow obstruction in inner-city children with asthma persists despite guideline-based asthma care. Methods: In a retrospective study that used a cohort of inner-city children with asthma treated by using an asthma-specific disease management system, the patients were stratified into “low” or “high” lung function groups at the time of the initial visit (high, forced expiratory volume in the first second of expiration [FEV1] % predicted and FEV1/forced vital capacity [FVC] ≥ 80%; and low, FEV1% predicted and FEV1/FVC < 80%). These patients then received National Heart, Lung, and Blood Institute guideline‐based asthma treatment at regular follow-up intervals with spirometry performed at these visits as part of regular care. FEV1% predicted and FEV1/FVC were followed up for up to 10 years for both the high and low cohorts. Results: Over 10 years, the patients initially in the “high” group maintained FEV1% predicted and FEV1/FVC at values similar to the initial visit (94 to 96% and 87 to 89%, respectively), whereas those in the low group had only slight increases of FEV1% predicted and FEV1/FVC over the same time (77 to 82% and 78 to 82%, respectively). Low FEV1% predicted and FEV1/FVC at the time of the first visit was significantly associated with an increased risk of low values of these lung functions over the next 3‐5 years despite treatment. African American ethnicity and male gender were also associated with lower lung function over time. Conclusion: Early airflow obstruction in inner city children asthma is associated with poor lung function in later life despite guideline-based asthma care. Current asthma therapy may not affect pathways and leads to airway remodeling in children with asthma.

Background and objectiveThe relationship between hospitalisation with an eosinophilic acute exacerbation of COPD (AE-COPD) and future relapses is unclear. We aimed to explore this association by following 152 patients for 12 months after hospital discharge or until their first moderate or severe flare-up.MethodsPatients hospitalised with AE-COPD were divided into eosinophilic and non-eosinophilic groups based on full blood count results on admission. All patients were treated with a course of systemic corticosteroid. The Cox proportional hazards model was used to study the association with the time to first re-exacerbation; a generalised linear regression model was applied to identify clinical variables related to the recurrence of relapses.ResultsWe did not find a difference in the time to the next moderate or severe exacerbation between the eosinophilic (≥2% of total leukocytes and/or ≥200 eosinophils·µL−1, n=51, median (interquartile range): 21 (10–36) weeks) and non-eosinophilic groups (n=101, 17 (9–36) weeks, log-rank test: p=0.63). No association was found when other cut-off values (≥3% of total leukocytes and/or ≥300 eosinophils·µL−1) were used for the eosinophilic phenotype. However, the higher number of past severe exacerbations, a lower forced expiratory volume in 1 s (FEV1) at discharge and higher pack-years were related to shorter exacerbation-free time. According to a subgroup analysis (n=73), 48.1% of patients with initial eosinophilic exacerbations had non-eosinophilic relapses on readmission.ConclusionsOur data do not support an increased risk of earlier recurring moderate or severe relapses in patients hospitalised with eosinophilic exacerbations of COPD. Eosinophilic severe exacerbations present a variable phenotype.

We modified an algorithm for mechanical ventilation of infants with respiratory distress syndrome to create an interactive user-friendly computer program. To determine the effectiveness of this computer program, we evaluated the correction of deranged arterial blood gases in three groups of neonates: group I, treated before the introduction of the computer into the nursery; group II, managed by pediatric residents with the guidance of the computer program; group III, treated after the introduction of the computer into the nursery but managed without consideration of the computer output. Arterial blood gas values improved more frequently in the neonates managed with computer consultation (group II, 65/75, 87%) than in both control groups (group I, 37/57, 65%, P &lt; .005; and group III, 46/63, 73%, P &lt; .05). Furthermore, increases in ventilatory support in the presence of normal arterial blood gas values occurred only in patients managed without computer guidance. In a teaching institution, more effective care of neonates with respiratory failure may be facilitated by computer-assisted management of mechanical ventilators.

Abstract Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) is often performed in patients with primary sclerosing cholangitis (PSC). Our aim was to validate a treatment approach with the objective of decreasing ERCP related adverse events (AEs). Patients and methods All patients who had undergone ERCP for PSC during the period from 2002 – 2012 were identified (group I). This group had traditional ERCP (no bile aspiration prior to contrast injection with balloon dilation and stent placement for treatment of dominant strictures). To decrease ERCP-related AEs, we changed the ERCP approach in which bile aspiration was performed prior to contrast injection and balloon dilation alone was performed for treatment of dominant strictures. This was tested prospectively in all patients undergoing ERCP for PSC from 2012 – 2014 (group II). Results The risk of overall AEs and cholangitis was relatively less in group II compared with group I [(2.1 % vs. 10.3 %; P = .38) and (0 % vs. 4.4 %; P = .68)]. On bivariate analysis, change in ERCP approach was associated with decreased risk of post-procedure cholangitis (0 % vs. 10.2 %, P = .03) and overall AE (0 % vs. 18.6 %, P = .03). There were no AEs in 22/46 patients in group II who had bile aspiration with balloon dilation. On multivariate analysis, only biliary stent placement was associated with increased risk of AEs (OR 4.10 (1.32 – 12.71); P = .02) and cholangitis (OR 5.43, 1.38 – 21.38; P = .02) respectively. Conclusion Biliary aspiration and avoidance of stenting approach after dilation of strictures during ERCP in PSC patients appears to be associated with decreased risk of cholangitis and overall AEs. Future prospective randomized controlled trials are needed to validate our observation.

Environmental and occupational exposure to benzene from fuels is a major cause for concern for national and international authorities, as benzene is a known carcinogen in humans and there is no safe limit for exposure to carcinogens. The objective of this study was to evaluate the genotoxic effects of chronic occupational exposure to benzene among two groups of workers: filling station workers (Group I) and security guards working at vehicles entrances (Group II), both on the same busy highway in Rio de Janeiro, Brazil. Sociodemographic data on the workers were evaluated; the concentration of benzene/toluene (B/T) in atmospheric air and individual trans,trans-muconic acid (ttMA) and S-phenylmercapturic acid (S-PMA) were measured; oxidative stress was analyzed by catalase (CAT), glutathione S-transferase (GST), superoxide dismutase (SOD), thiol groups (THIOL) and malondialdehyde (MDA); genotoxicity was measured by metaphases with chromosomal abnormalities (MCA) and nuclear abnormalities, comet assay using the enzyme formamidopyrimidine DNA glycosylase (C-FPG), and methylation of repetitive element LINE-1, CDKN2B and KLF6 genes. Eighty-six workers participated: 51 from Group I and 35 from Group II. The B/T ratio was similar for both groups, but Group I had greater oscillation of benzene concentrations because of their work activities. No differences in ttMA and S-PMA, and no clinical changes were found between both groups, but linearity was observed between leukocyte count and ttMA; and 15% of workers had leukocyte counts less than 4.5 × 109 cells L−1, demanding close worker’s attention. No differences were observed between the two groups for THIOL, MDA, MCA, or nuclear abnormalities. A multiple linear relationship was obtained for the biomarkers MCA and C-FPG. A significant correlation was found between length of time in current job and the biomarkers C-FPG, MCA, GST, and MDA. Although both populations had chronic exposure to benzene, the filling station workers were exposed to higher concentrations of benzene during their work activities, indicating an increased risk of DNA damage.

Heparin Prophylaxis

Abstract Women with a history of VTE, thrombophilia or both are at increased risk for VTE during pregnancy, but the optimal management strategy, and the need for thromboprophylaxis is not well defined in clinical guidelines because of limited trial data. The EThIG (Efficacy of Thromboprophylaxis as an Intervention during Gravidity) is a multicenter trial that prospectively enrolled 810 pregnant women at risk of VTE. Women were assigned to one of 3 management strategies: Low risk group I (including women with prior secondary VTE, or asymptomatic thrombophilia) with “watchful waiting” management, and dalteparin prophylaxis postpartum (50–100 IU/kg), or earlier if additional risk factors occurred; high risk group II (e.g. idiopathic VTE or symptomatic thrombophilia) receiving 50–100 IU/kg dalteparin; and very high-risk group III (e.g. acute VTE, prior long-term OAC, symptomatic AT-deficiency or antiphospholipid syndrome), receiving 100–200 IU/kg dalteparin. Primary efficacy outcome measure was symptomatic VTE, main safety outcome measures were haemorrhages, osteoporosis, thromboctopenia and pregnancy outcome. Results (mean ± SD / 95% CI): 810 women (age 30.8±5.4 years, weight 73.6±16.1kg) were enrolled, 28 % in group I, 58 % in II and 14% in III, including 66 women with acute VTE. 60.1% had prior VTE, 75.4% had thrombophilia (42.1 % FV-Leiden, 2.1 % homozygous, 9.5 % FII G20210A, 4.1% PC-, 1 % AT-deficiency; 17.4 % APS). 35.8 % had previous miscarriage, still birth or physical malformation. Comorbid conditions included lupus erythematosus, liver transplantation, ventricular septum defect, paraplegia, hepatitis C, nephrotic syndrome, asthma, chronic haemolytic anaemia, thalassaemia, osteoporosis and thrombocytopaenia. Median treatment initiation was at 17.0 weeks, at 24.0 weeks in group I, 14.5 weeks in group II and 16.0 weeks for group III. Mean daily dose was 66.2 ± 22.5 IU per kg (group I), 76.8 ± 24.1 IU per kg (group II) and 120.0 ± 49.1 IU per kg (group III). Objectively confirmed, symptomatic VTE occurred in 5 of 810 women (0.6%;0.2–1.5%). The rate of serious bleeding was 3.0% (1.9–4.4%), 0.9% (0.3–1.8%) occurred in the antepartum period, 2.1% (1.3–3.4%) peri-partum;1.1% (0.5–2.2%) was possibly heparin-related. There was no evidence of heparin-induced thrombocytopenia, and one case of osteoporosis (fracture of the saccygous bone during delivery). There were 94.4% successful pregnancies, 40 foetuses (4.9%; 3.6–6.7%) were lost due to miscarriage, 7 due to elective termination. Risk-stratified heparin prophylaxis was associated with a low incidence of symptomatic venous thromboembolism and few clinically important adverse events. Antepartum heparin prophylaxis is warranted in pregnant women with prior idiopathic thrombosis or symptomatic thrombophilia.

Abstract Background This study aims to detect the effects of increased BMI on labor outcomes in primigravida pregnant women. Methods A cross-sectional study involved 600 full-term singleton primigravida pregnant women who presented in the active phase of labor to the labor ward. They were divided according to BMI into three equals groups; women with normal BMI (group I), overweight women (group II), and women with class I obesity (group III). Results We found that high BMI was associated with a significantly increased risk of Caesarean section (C.S.) (13% in group I, 18% in group II and 40% in group III). Women with higher BMI and delivered vaginally had a significantly prolonged first and second stage of labor, consequently increased the need for oxytocin augmentation as well as the oxytocin dose. Regarding the maternal and fetal outcomes, there are significantly increased risks of postpartum sepsis, perineal tears, wound infection, as well as significantly increased birth weight and longer neonatal stay in the neonatal unit (NNU). Conclusion Obese primigravida pregnant women were at higher risk of suboptimal outcomes. Besides, prolonged first and second stages of labor and the incidence of C.S. have also been increased.

Abstract INTRODUCTION Polypharmacy of respiratory medications is commonly seen in COPD patients. Reduction of COPD therapy in patients with overtreatment may have benefits by providing adherence to the guideline recommendations. We aimed to investigate effects of treatment de-escalation in COPD. METHODS This multi-center, prospective study was carried out in four pulmonary outpatient clinics. Overtreated patients (according to GOLD 2017) were recommended to undergo de-escalation of treatment (reduction group I), and those who were under appropriate treatment were recommended a stepwise de-escalation (reduction group II). Patients who declined de-escalation were in non-reduction group I. Non-reduction group II consisted of patients under appropriate treatment. Inhalation device skill, symptom control and quality of life (QOL) were assessed at baseline and 6-month follow-up. RESULTS At baseline visit, 55.9% of participants (76/136) were overtreated. There were de-escalation in 54 patients (35: reduction group I, 19: reduction group II). Non- reduction groups I and II included 37 and 45 patients, respectively. FEV 1 of patients with appropriate treatment improved significantly (p=0.033). There was a significant improvement in QOL in reduction group I (p=0.005) and II (p=0.011). Patients who reduced/quitted smoking during follow-up recorded significant improvements in FEV 1 and drug inhalation skills score (p=0.034 and p=0.023, respectively). Overtreatment had an estimated additional cost of 119.57$/year for each patient. CONCLUSION Overtreatment is a common problem in COPD. De-escalation of inhaler medications can improve QOL. Appropriate treatment according to guidelines positively affects respiratory parameters. Reduction/discontinuation of smoking improves both inhaler adherence and spirometric measurements. De-escalation of inhaler treatment should be considered in overtreated patients.

This article presents data on the frequency of incidence and duration of cardiovascular dysfunction in children with acute respiratory failure. The information on expediency of carrying out of personalized hemodynamic management in case of its insufficiency with use of multiparametric approach to estimate haemodynamic data are presented. The aim of the study was to compare the effectiveness of the standard approach and proposed by us additions to treatment of haemodynamic disorders in children with respiratory failure. It was summarized from the literature reviews that the presence and maintenance of patient`s spontaneous breathing pattern with use of non-invasive estimated cardiovascular monitoring, evaluation of preload with ultrasonography and reassessment of rate and volume of fluid replacement with taking into account solution`s composition might improve treatment results in children with acute respiratory failure. We conducted a prospective single-center non-interventional cohort study in children with acute respiratory failure 1 month - 18 years old. Patients were randomly divided into I and II groups. The data analysis included 43 patients of group I, who received conventional for this intensive care unit monitoring and treatment and 53 patients of group II, in whom we took into account the results of multiparametric monitoring during the correction of hemodynamics.Monitoring of hemodynamics included heart rate, non-invasive systolic, diastolic and mean blood pressure capillary refill time and presence of peripheral arteries pulsation with clinical verification of "warm" or "cold" shock, ScvO2 and lactate levels in the central venous blood; non-invasive estimated monitoring of stroke volume, cardiac output, cardiac index, stroke index using the esCCO technology, NIHON COHDEN (Japan) and the ratio of inferior vena cava diameter at inspiration and exhalation. Hemodynamic support in groups I and II included early goal-directad therapy, individualized and personalized treatment. In II group of patients there were taken into account the dynamics of changes of non-invasive esCCO data about stroke volume, cardiac output, cardiac index and stroke index, cumulative hydrobalance and the ratio of the of inferior vena cava diameter at inspiration and exhalation. Early goal-directed therapy was aimed to (supra) normalize of blood flow and was based on normal hemodynamic data for population, according to percentiles for specific age groups of patients. Individualized hemodynamic therapy included functional hemodynamic monitoring with assessment of to volemic therapy answer, individualization of target points and maximization of blood flow. Personalized hemodynamic management consisted of applying an adaptive multiparametric approach to hemodynamic assessment. Spontaneous diaphragmatic activity was maintained along all time of mechanical ventilation. The primary endpoint was 28-day mortality rate; secondary endpoints were the duration of cardiovascular dysfunction and the duration of intensive care unit stay. To assess age-dependent data, patients were divided into age subgroups: 1st subgroup - children 1 month - 1 year old; 2nd subgroup - children 1 - 3 years old; 3rd subgroup - children 3 - 6 years old; 4th subgroup - children 6 - 12 years old; 5th subgroup - children 12 - 18 years old. It was determined that the level of 28-day mortality was: in 1st age subgroup - 18.2% in group I and 3.1% in group II (p = 0.02), in the 2nd age subgroup - 11.1% and 0%, respectively (p = 0.11); in the 4th age subgroup - 10% and 0%, respectively (p = 0.28); in the 3rd and 5th age subgroups - was 0% in I and II groups. The prevalence of hemodynamic disorders was: in 1st age subgroup in patients of group I - 100%, while in group II - 62.5% (p = 0.001); in 2nd age subgroup - 55.6% in patients from group I and 42.9% in patients from group II (p = 0.05); in 3rd age subgroup in 100% of patients of group II and only in 75% of patients of group I (p = 0.02). In the 4th age subgroup no significant differences were found between I (30% of patients) and II groups (25% of patients), p = 0.28; in 5th age subgroup the frequency of cardiovascular dysfunction was 40% in group I, compared with 75% in group II (p = 0.008). It was found that duration of hemodynamic insufficiency was longer in patients of 1st and 4th age subgroups, and relatively shorter in patients of 5th age subgroup: in the 1st age subgroup it was 7.6 ± 0.5 days in group I and 8.8 ± 0.9 days in group II (p> 0.05); in 4th age subgroup - 6.7 ± 0.4 days in group I and 10.1 ± 1.2 days in group II (p> 0.05), while in 5th age subgroup - 4.1 ± 0.3 days in group I and 4.7 ± 0.5 days in group II (p> 0.05). We found that there were significant differences in the duration of stay in intensive care unit among patients of the 1st and 5th age subgroups. Specifically, in 1st age subgroup this indicator was in 1.3 times less in group II, compared with group I (p <0.05); in 5th age subgroup the situation was the opposite- the duration of intensive care unit stay in group II was in 1.4 times more in group I (p <0.05). Thus, obtained data demonstrated the results of the use of personalized management of hemodynamic disorders in children with acute respiratory failure. The use of a multiparametric approach to hemodynamic assessment in clinical practice may allow more differentiated use of volume replacement therapy as loop diuretics and will have a beneficial effect on the final clinical outcomes in patients with acute respiratory failure.

RationaleChronic obstructive pulmonary disease (COPD) comprises distinct phenotypes, all characterised by airflow limitation.ObjectivesWe hypothesised that somatotype changes – as a surrogate of adiposity – from early adulthood follow different trajectories to reach distinct phenotypes.MethodsUsing the validated Stunkard's Pictogram, 356 COPD patients chose the somatotype that best reflects their current body build and those at ages 18, 30, 40 and 50 years. An unbiased group-based trajectory modelling was used to determine somatotype trajectories. We then compared the current COPD-related clinical and phenotypic characteristics of subjects belonging to each trajectory.Measurements and main resultsAt 18 years of age, 88% of the participants described having a lean or medium somatotype (estimated body mass index (BMI) between 19 and 23 kg·m−2) while the other 12% a heavier somatotype (estimated BMI between 25 and 27 kg·m−2). From age 18 onwards, five distinct trajectories were observed. Four of them demonstrating a continuous increase in adiposity throughout adulthood with the exception of one, where the initial increase was followed by loss of adiposity after age 40. Patients with this trajectory were primarily females with low BMI and DLCO (diffusing capacity of the lung for carbon monoxide). A persistently lean trajectory was seen in 14% of the cohort. This group had significantly lower forced expiratory volume in 1 s (FEV1), DLCO, more emphysema and a worse BODE (BMI, airflow obstruction, dyspnoea and exercise capacity) score thus resembling the multiple organ loss of tissue (MOLT) phenotype.ConclusionsCOPD patients have distinct somatotype trajectories throughout adulthood. Those with the MOLT phenotype maintain a lean trajectory throughout life. Smoking subjects with this lean phenotype in early adulthood deserve particular attention as they seem to develop more severe COPD.
