    Patient-reported signs of dampness at home may be a risk factor for chronic rhinosinusitis: A cross-sectional study2017In: Clinical and Experimental Allergy, ISSN 0954-7894, E-ISSN 1365-2222, Vol. 47, no 11, p. 1383-1389Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: An association between dampness at home and respiratory conditions has been convincingly demonstrated in children. Fewer studies have been performed in adults, and data are lacking for chronic rhinosinusitis (CRS). With a prevalence of 10.9% in Europe, CRS imposes a significant burden on quality of life, as well as economy.

    OBJECTIVE: Our aim was to study CRS and other respiratory conditions in relation to dampness at home in a representative sample of adults.

    METHODS: The Swedish GA2 LEN questionnaire was answered by 26 577 adults (16-75 years) and included questions on respiratory symptoms, smoking, education and environmental exposure. CRS was defined according to the EP3 OS criteria. Dampness was defined as reporting water damage, floor dampness or visible moulds in the home during the last 12 months. The dampness score was ranked from 0 to 3, counting the number of signs of dampness reported.

    RESULTS: Dampness at home was reported by 11.3% and was independently related to respiratory conditions after adjustment for demographic and socio-economic factors and smoking: CRS odds ratio (OR) 1.71; allergic rhinitis OR 1.24; current asthma OR 1.21; wheeze OR 1.37; nocturnal dyspnoea OR 1.80; nocturnal coughing OR 1.34; and chronic bronchitis OR 1.64. The risk of CRS and most of the other respiratory conditions was further elevated in subjects reporting multiple signs of dampness.

    CONCLUSIONS AND CLINICAL RELEVANCE: This study demonstrated an independent association between dampness at home and CRS in adults. The high burden of this and the other respiratory conditions studied is a strong argument in favour of countering indoor dampness by improving building standards.

    WHO Needs High FIO2?2017In: TURKISH JOURNAL OF ANAESTHESIOLOGY AND REANIMATION, ISSN 2149-0937, Vol. 45, no 4, p. 181-192Article in journal (Refereed)
    Abstract [en]

    World Health Organization and the United States Center for Disease Control have recently recommended the use of 0.8 FIO2 in all adult surgical patients undergoing general anaesthesia, to prevent surgical site infections. This recommendation has arisen several discussions: As a matter of fact, there are numerous studies with different results about the effect of FIO2 on surgical site infection. Moreover, the clinical effects of FIO2 are not limited to infection control. We asked some prominent authors about their comments regarding the recent recommendations

    Effects of propofol anaesthesia on thoraco-abdominal volume variations during spontaneous breathing and mechanical ventilation2011In: Acta Anaesthesiologica Scandinavica, ISSN 0001-5172, E-ISSN 1399-6576, Vol. 55, no 5, p. 588-596Article in journal (Refereed)
    Abstract [en]

    Background Anaesthesia based on inhalational agents has profound effects on chest wall configuration and breathing pattern. The effects of propofol are less well characterised. The aim of the current study was to evaluate the effects of propofol anaesthesia on chest wall motion during spontaneous breathing and positive pressure ventilation. Methods We studied 16 subjects undergoing elective surgery requiring general anaesthesia. Chest wall volumes were continuously monitored by opto-electronic plethysmography during quiet breathing (QB) in the conscious state, induction of anaesthesia, spontaneous breathing during anaesthesia (SB), pressure support ventilation (PSV) and pressure control ventilation (PCV) after muscle paralysis. Results The total chest wall volume decreased by 0.41 +/- 0.08 l immediately after induction by equal reductions in the rib cage and abdominal volumes. An increase in the rib cage volume was then seen, resulting in total chest wall volumes 0.26 +/- 0.09, 0.24 +/- 0.10, 0.22 +/- 0.10 l lower than baseline, during SB, PSV and PCV, respectively. During QB, rib cage volume displacement corresponded to 34.2 +/- 5.3% of the tidal volume. During SB, PSV and PCV, this increased to 42.2 +/- 4.9%, 48.2 +/- 3.6% and 46.3 +/- 3.2%, respectively, with a corresponding decrease in the abdominal contribution. Breathing was initiated by the rib cage muscles during SB. Conclusion Propofol anaesthesia decreases end-expiratory chest wall volume, with a more pronounced effect on the diaphragm than on the rib cage muscles, which initiate breathing after apnoea.

    Impact of the 2016 ASE/EACVI recommendations on the prevalence of diastolic dysfunction in the general population2018In: European Heart Journal Cardiovascular Imaging, ISSN 2047-2404, E-ISSN 2047-2412, Vol. 19, no 4, p. 380-386Article in journal (Refereed)
    Abstract [en]

    Aims: Diastolic dysfunction (DD) is frequent in the general population; however, the assessment of diastolic function remains challenging. We aimed to evaluate the impact of the recent 2016 American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) recommendations in the prevalence and grades of DD compared with the 2009 guidelines and the Canberra Study Criteria (CSC).

    Methods and results: Within a population-based cohort, a total of 1000 individuals, aged ≥45 years, were evaluated retrospectively. Patients with previously known cardiac disease or ejection fraction <50% were excluded. Diastolic function was assessed by transthoracic echocardiography. DD prevalence and grades were determined according to the three classifications. The mean age was 62.0 ± 10.5 years and 37% were men. The prevalence of DD was 1.4% (n = 14) with the 2016 recommendations, 38.1% (n = 381) with the 2009 recommendations, and 30.4% (n = 304) using the CSC. The concordance between the updated recommendations and the other two was poor (from k = 0.13 to k = 0.18, P < 0.001). Regarding the categorization in DD grades, none of the 14 individuals with DD by the 2016 guidelines were assigned to Grade 1 DD, 64% were classified as Grade 2, 7% had Grade 3, and 29% had indeterminate grade.

    Conclusion: The application of the new 2016 ASE/EACVI recommendations resulted in a much lower prevalence of DD. The concordance between the classifications was poor. The updated algorithm seems to be able to diagnose only the most advanced cases.

    Important non-disease-related determinants of exhaled nitric oxide levels in mild asthma - results from the Swedish GA(2)LEN study2016In: Clinical and Experimental Allergy, ISSN 0954-7894, E-ISSN 1365-2222, Vol. 46, no 9, p. 1185-1193Article in journal (Refereed)
    Abstract [en]

    Background Fractional exhaled nitric oxide (FeNO) has a potential clinical role in asthma management. Constitutive factors such as age, height and gender, as well as individual characteristics, such as IgE sensitization and smoking, affect the levels of FeNO in population-based studies. However, their effect on FeNO in subjects with asthma has been scarcely studied. Objective To study the effects on FeNO of these commonly regarded determinants, as demonstrated in healthy subjects, as well as menarche age and parental smoking, in a population of asthmatics. Material and Methods Fractional exhaled nitric oxide was measured in 557 subjects with asthma from the Swedish GA(2)LEN study. Allergic sensitization was assessed by skin prick tests to most common aeroallergens. Upper airway comorbidities, smoking habits, smoking exposure during childhood and hormonal status (for women) were questionnaire-assessed. Results Male gender (P < 0.001), greater height (P < 0.001) and sensitization to both perennial allergens and pollen (P < 0.001) are related to higher FeNO levels. Current smoking (P < 0.001) and having both parents smoking during childhood, vs. having neither (P < 0.001) or only one parent smoking (P = 0.002), are related to lower FeNO. Women with menarche between 9 and 11 years of age had lower FeNO than those with menarche between 12 and 14 years of age (P = 0.03) or 15 and 17 years of age (P = 0.003). Conclusions and Clinical relevance Interpreting FeNO levels in clinical practice is complex, and constitutional determinants, as well as smoking and IgE sensitisation, are of importance in asthmatic subjects and should be accounted for when interpreting FeNO levels. Furthermore, menarche age and parental smoking during childhood and their effects on lowering FeNO deserve further studies.

    Basic aspects of exhaled nitric oxide2010In: European Respiratory Monograph, ISSN 1025-448X, E-ISSN 2075-6674, Vol. 49, p. 1-31Article, review/survey (Refereed)
    Abstract [en]

    Nitric oxide (NO) in orally exhaled air mainly originates fromthe respiratory epithelium. NO is produced by inducible NOsynthase (iNOS), which is regulated by signal transducer andactivator of transcription (STAT)-1 under the influence ofhomeostatic interferon-c. In patients with asthma, iNOSexpression is upregulated by interleukin (IL)-4 and IL-13 viathe activation of STAT-6 in the bronchial epithelium. Thus,exhaled NO primarily signals local T-helper cell type 2-driveninflammation in the bronchial mucosa. With these character-istics, exhaled NO will be a suitable marker for predicting theresponse to inhaled corticosteroids, and to monitor the anti-inflammatory effect.The methodology for measuring exhaled NO has beenstandardised based on international consensus. The determi-nants of exhaled NO levels are fairly well characterised, withthe most important being cigarette smoking, nitrate intake, airpollution, allergen sensitisation and exposure, along withheight, sex and age. A future development may be the estima-tion of peripheral airway inflammation by measuring exhaledNO at multiple exhalation flow rates.

    Having concomitant asthma phenotypes is common and independently relates to poor lung function in NHANES 2007-20122018In: Clinical and Translational Allergy, ISSN 2045-7022, E-ISSN 2045-7022, Vol. 8, article id 13Article in journal (Refereed)
    Abstract [en]

    Background: Evidence for distinct asthma phenotypes and their overlap is becoming increasingly relevant to identify personalized and targeted therapeutic strategies. In this study, we aimed to describe the overlap of five commonly reported asthma phenotypes in US adults with current asthma and assess its association with asthma outcomes. Methods: Data from the National Health and Nutrition Examination Surveys (NHANES) 2007-2012 were used (n =30,442). Adults with current asthma were selected. Asthma phenotypes were: B-Eos-high [if blood eosinophils (B-Eos) >= 300/mm(3)]; FeNO-high (FeNO >= 35 ppb); B-Eos&FeNO-low (B-Eos < 150/mm(3) and FeNO < 20 ppb); asthma with obesity (AwObesity) (BMI >= 30 kg/m(2)); and asthma with concurrent COPD. Data were weighted for the US population and analyses were stratified by age (< 40 and >= 40 years old). Results: Of the 18,619 adults included, 1059 (5.6% [95% CI 5.1-5.9]) had current asthma. A substantial overlap was observed both in subjects aged < 40 years (44%) and >= 40 years (54%). The more prevalent specific overlaps in both age groups were AwObesity associated with either B-Eos-high (15 and 12%, respectively) or B-Eos&FeNO-low asthma (13 and 11%, respectively). About 14% of the current asthma patients were"non-classified". Regardless of phenotype classification, having concomitant phenotypes was significantly associated with (adjusted OR, 95% CI) >= 2 controller medications (2.03, 1.16-3.57), and FEV1 < LLN (3.21, 1.74-5.94), adjusted for confounding variables. Conclusions: A prevalent overlap of commonly reported asthma phenotypes was observed among asthma patients from the general population, with implications for objective asthma outcomes. A broader approach may be required to better characterize asthma patients and prevent poor asthma outcomes.

    Excessive daytime sleepiness in asthma: what are the risk factors?2016In: Journal of Asthma, ISSN 0277-0903, E-ISSN 1532-4303Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: Previous studies have found that excessive daytime sleepiness (EDS) is a more common problem in asthmatic subjects than in the general population. The aim of this study was to investigate whether the prevalence of EDS is increased in asthmatic subjects and, if so, to analyse the occurrence of potential risk factors for EDS in asthmatics.

    METHODS: Cross-sectional epidemiological study. In 2008, a postal questionnaire was sent out to a random sample of 45,000 individuals aged 16-75 years in four Swedish cities.

    RESULTS: Of the 25,160 persons who participated, 7.3% were defined as having asthma. The prevalence of EDS was significantly higher in asthmatic subjects (42.1% vs 28.5%, p<0.001) compared with non-asthmatic subjects. Asthma was an independent risk factor for EDS (adjusted OR 1.29) and the risk of having EDS increased with asthma severity. Risk factors for EDS in subjects with asthma included insomnia (OR, 3.87; 95% CI, 3.10-4.84), chronic rhinosinusitis (OR, 2.00; 95% CI, 1.53-2.62), current smoking (OR, 1.60; 95% CI, 1.15-2.22) and obesity (OR, 1.53; 95% CI, 1.09-2.13).

    CONCLUSIONS: EDS is a common problem among subjects with asthma. Asthma is an independent risk factor for having EDS. Furthermore, subjects with asthma often have other risk factors for EDS, many of them potentially modifiable.

    In Vivo Visualization of Amyloid Deposits in the Heart with 11C-PIB and PET2013In: Journal of Nuclear Medicine, ISSN 0161-5505, E-ISSN 1535-5667, Vol. 54, no 2, p. 213-220Article in journal (Refereed)
    Abstract [en]

    Cardiac amyloidosis is a differential diagnosis in heart failure and is associated with high mortality. There is currently no noninvasive imaging test available for specific diagnosis. N-[methyl-11C]2-(4′-methylamino-phenyl)-6-hydroxybenzothiazole (11C-PIB) PET is used in the evaluation of brain amyloidosis. We evaluated the potential use of 11C-PIB PET in systemic amyloidosis affecting the heart.

    Methods:

    Patients (n = 10) diagnosed with systemic amyloidosis—including heart involvement of either monoclonal immunoglobulin light-chain (AL) or transthyretin (ATTR) type—and healthy volunteers (n = 5) were investigated with PET/CT using 11C-PIB to study cardiac amyloid deposits and with 11C-acetate to measure myocardial blood flow to study the impact of global and regional perfusion on PIB retention.

    Results:

    Myocardial 11C-PIB uptake was visually evident in all patients 15–25 min after injection and was not seen in any volunteer. A significant difference in 11C-PIB retention in the heart between patients and healthy controls was found. The data indicate that myocardial amyloid deposits in patients diagnosed with systemic amyloidosis could be visualized with 11C-PIB. No correlation between 11C-PIB retention index and myocardial blood flow as measured with 11C-acetate was found on the global level, whereas a positive correlation on the segmental level was seen in a single patient.

    Conclusion:

    11C-PIB and PET could be a method to study systemic amyloidosis of type AL and ATTR affecting the heart and should be investigated further both as a diagnostic tool and as a noninvasive method for treatment follow-up.

    Lungefysioterapi ved abdominal- og thoraxkirurgi2011In: Fysioterapeuten, Vol. 9Article in journal (Other academic)
    Abstract [da]

    I snart hundrede år har fysioterapeuter arbejdet på at mindske risikoen for postoperative lungekomplikationer hos patienter, der skal opereres i brystkassen og abdominalregionen. Klinisk erfaring viser, at lungefysioterapi er vigtig, men hvad ved vi i dag om effekten af forskellige former for behandling? Hvilke indsatsområder skal man i første omgang vælge? Forfatterne til denne artikel har udarbejdet retningslinjer for lungefysioterapi til patienter, som gennemgår abdominal- og thoraxkirurgi. Målet med arbejdet med retningslinjerne har været at udrede og sammensætte eksisterende evidens for lungefysioterapeutiske behandlingsmetoder i forbindelse med abdominal- og thoraxkirurgiske indgreb.

    Den samlede evidens i kombination med ekspertgruppens kommentarer har ført til anbefalinger for den kliniske behandling. Disse anbefalinger er målrettet fysioterapeuter i den kliniske praksis, som arbejder med abdominal - og thoraxkirurgiske patienter. Sigtet er, at den aktuelle og systematisk indsamlede viden vil bidrage til diskussioner på de forskellige arbejdspladser, og at anbefalingerne for behandling vil blive tilpasset de lokale forhold. Denne artikel sammenfatter retningslinjerne, som er publiceret på fysioterapiforbundets (Legitimerede Sjukgymnasters) hjemmeside under profession. De kliniske retningslinjer omfatter desuden en komplet referenceliste.

    Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea2003Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Obstructive sleep apnea (OSA) appears to affect up to 5% of the population. The extent to what pulmonary function awake and during sleep relates to obstructive breathing and hypoxemia during sleep in these patients is unclear. The aim of this study was to investigate respiratory function in patients with varying degree of snoring and OSA and to analyse regional lung aeration during sleep.

    In all, 35 healthy subjects and 90 patients with snoring and OSA were studied. The ventilatory response to CO2 (VRCO2) was measured. Lung function tests were performed. A technique based on computed tomography was developed to study lung aeration during sleep.

    Patients with OSA displayed a higher VRCO2 in comparison to healthy subjects and snorers (p<0.01). Increased closing volume and reduced expiratory reserve volume (ERV) were found in patients with OSA (p<0.001). In a multiple regression analysis, ERV was an independent predictor of nocturnal apnea (R2=0.13; p=0.001) and desaturation frequency (R2=0.11; p<0.01). In both healthy subjects and OSA patients, lung aeration was reduced during sleep by 0.10 ml gas/g tissue in the dorsal lung region (p<0.05 and p<0.01). OSA patients had a significantly lower gas/tissue ratio in comparison to healthy subjects both awake (-23%; p<0.04) and during sleep (-25%; p<0.04). In a univariate analysis, functional residual capacity (FRC) correlated with the change in lung aeration from wakefulness to sleep (r=-0.78; p<0.001). In patients with OSA, ERV (r=-0.69; p<0.05) and sleep time (r=0.69; p<0.05) correlated with the fall in lung aeration.

    In conclusion, patients with OSA display an increased ventilatory response to CO2, reduced ERV and increased closing volume. ERV predicts nocturnal apnea and desaturation frequency to a similar extent as obesity. Lung aeration is reduced in the dorsal region during sleep and patients with OSA display a lower amount of gas in comparison to healthy subjects. Decrease in lung volumes, promoting airway closure, and loss of muscle tone contributed to the altered lung function during sleep.

    Abstract [en]

    Background: During sleep, ventilation and functional residual capacity (FRC) decrease slightly. This study addresses regional lung aeration during wakefulness and sleep. Methods: Ten healthy subjects underwent spirometry awake and with polysomnography, including pulse oximetry, and also CT when awake and during sleep. Lung aeration in different lung regions was analyzed. Another three subjects were studied awake to develop a protocol for dynamic CT scanning during breathing. Results: Aeration in the dorsal, dependent lung region decreased from a mean of 1.14 ± 0.34 mL (± SD) of gas per gram of lung tissue during wakefulness to 1.04 ± 0.29 mL/g during non-rapid eye movement (NREM) sleep (- 9%) [p = 0.034]. In contrast, aeration increased in the most ventral, nondependent lung region, from 3.52 ± 0.77 to 3.73 ± 0.83 mL/g (+ 6%) [p = 0.007]. In one subject studied during rapid eye movement (REM) sleep, aeration decreased from 0.84 to 0.65 mL/g (- 23%). The fall in dorsal lung aeration during sleep correlated to awake FRC (R2 = 0.60; p = 0.008). Airway closure, measured awake, occurred near and sometimes above the FRC level. Ventilation tended to be larger in dependent, dorsal lung regions, both awake and during sleep (upper region vs lower region, 3.8% vs 4.9% awake, p = 0.16, and 4.5% vs 5.5% asleep, p = 0.09, respectively). Conclusions: Aeration is reduced in dependent lung regions and increased in ventral regions during NREM and REM sleep. Ventilation was more uniformly distributed between upper and lower lung regions than has previously been reported in awake, upright subjects. Reduced respiratory muscle tone and airway closure are likely causative factors.

    Lung aeration during sleep in patients with obstructive sleep apnoea2010In: Clinical Physiology and Functional Imaging, ISSN 1475-0961, E-ISSN 1475-097X, Vol. 30, no 4, p. 301-307Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Previous studies have indicated that patients with obstructive sleep apnoea (OSA) have altered ventilation and lung volumes awake and the results suggest that this may be a determinant of severity of desaturations during sleep. However, little is known about regional lung aeration during sleep in patients with OSA. METHODS: Twelve patients with OSA were included in the study. Computed tomography was used to study regional lung aeration during wakefulness and sleep. Lung aeration was calculated in ml gas/g lung tissue in four different regions of interest (ROI(1-4)), along the border of the lung from ventral to dorsal. RESULTS: Lung aeration in the dorsal (dependent) lung region (ROI(4)) was lower during sleep compared to wakefulness 0.78 +/- 0.19 versus 0.88 +/- 0.19 (mean +/- SD) ml gas/g lung tissue (P = 0.005). Associations were found between awake expiratory reserve volume and change in lung aeration from wakefulness to sleep in ROI(4) (r = -0.69; P = 0.012). In addition, the change in lung aeration in the dorsal region correlated to sleep time (r = 0.69; P = 0.014) but not to time in supine position. The difference in lung aeration between inspiration and expiration (i.e. ventilation), was larger in the ventral lung region when expressed as ml gas per g lung tissue. In two patients it was noted that, during on-going obstructive apnoea, lung aeration tended to be increased rather than decreased. CONCLUSIONS: Aeration in the dorsal lung region is reduced during sleep in patients with OSA. The decrease is related to lung volume awake and to sleep time.

    Abstract [en]

    Background: During sleep, ventilation and functional residual capacity (FRC) decrease slightly. This study addresses regional lung aeration during wakefulness and sleep. Methods: Ten healthy subjects underwent spirometry awake and with polysomnography, including pulse oximetry, and also CT when awake and during sleep. Lung aeration in different lung regions was analyzed. Another three subjects were studied awake to develop a protocol for dynamic CT scanning during breathing.

    Smokeless Tobacco (Snus) and Outcome of Myocardial Infarction: a SWEDEHEART StudyManuscript (preprint) (Other academic)
    Abstract [en]

    Background

    Based on effects of nicotine and snus (a smokeless tobacco) on hemodynamics, pro-arrhythmia and remodelling, in combination with indications of increased risk for fatal myocardial infarction (MI) in snus users; we hypothesised that the outcome of an MI may be worse in snus users.

    Methods

    Data was extracted from the SWEDEHEART registry for all patients who underwent coronary angiography in Sweden due to MI between December 2009 and December 2014. In snus users (n=4,950) relative to snus non-users (n=55,412), we compared risks of a large MI (defined as hs-cTnT of  > 10,000 ng/L, cTnT > 10 μg/L or cTnI > 10 μg/L) and death in the acute (in-hospital) setting, and death+HF (a combined endpoint of all-cause death or hospitalization for heart failure) and all-cause death at short- (<28 days) and long-term follow-up. Relations of snus use to outcomes were also analysed in pre-specified subgroups of never, previous and current smokers.

    Results

    A large MI was diagnosed in 10,975 patients. During long-term follow-up (median 1.9 years), 7,758 either died (n=6,044) or were hospitalized due to heart failure (n=1,714). In models adjusting for age, gender, smoking, previous MI and occupational classification (employed, unemployed/sick leave and retired), snus use was not associated with risk of large MI (odds ratio 1.01; 95% confidence interval (CI) 0.93-1.09) or death+HF (long-term Cox proportional hazard ratio (HR) 0.99; 95% CI 0.90-1.10). Nonetheless, among never-smokers snus use was associated with an increased risk for death+HF (long-term HR 1.26, 95% CI 1.03-1.55), driven by a higher mortality risk (long-term HR for death of any cause 1.29, 95% CI 1.02-1.64).

    Conclusions

    In this study, snus use was unrelated to acute, short-term or long-term adverse outcomes after an MI. Among never-smokers, snus use was associated with an increased risk of post-MI death.

    Interval training compared with continuous training in patients with COPD2007In: Respiratory Medicine, ISSN 0954-6111, E-ISSN 1532-3064, Vol. 101, no 6, p. 1196-1204Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to compare the effects of interval training (3-min intervals) with continuous training on peak exercise capacity (W peak), physiological response, functional capacity, dyspnoea, mental health and health-related quality of life (HRQoL) in patients with moderate or severe COPD.

    Sixty patients exercised twice weekly for 16 weeks after randomisation to interval- or continuous training. Target intensity was 80% of baseline W peak in the interval group (I-group) and 65% in the continuous group (C-group). Patients were tested by spirometry, ergometer cycle test, cardiopulmonary test and a 12 min walk test. Dyspnoea was measured by the dyspnoea scale from Chronic Obstructive Disease Questionnaire (CRDQ), mental health by Hospital Anxiety and Depression scale (HAD) and HRQoL by the Medical Outcomes Survey Short Form 36 (SF-36).

    After training, W peak, peak oxygen uptake (VO2 peak) and exhaled carbon dioxide (VCO2 peak) increased significantly in both groups, no significant differences between the groups. Minute ventilation (VE peak) increased only in the C-group. At identical work rates (isotime) VO2, VCO2 and VE were significantly more decreased in the I-group than in the C-group (p<0.05). Functional capacity, dyspnoea, mental health, and HRQoL improved significantly in both groups, no difference between the groups.

    Interval training and continuous training were equally potent in improving peak exercise capacity, functional exercise capacity, dyspnoea, mental health and HRQoL in patients with moderate or severe COPD. At isotime, the physiological response to training differed between the groups, in favour of the interval training.

    How often is diagnosis of COPD confirmed with spirometry?2010In: Respiratory Medicine, ISSN 0954-6111, E-ISSN 1532-3064, Vol. 104, no 4, p. 550-556Article in journal (Refereed)
    Abstract [en]

    Background: Chronic obstructive pulmonary disease (COPD) is an important cause of morbidity and mortality worldwide. Diagnosis is customarily confirmed with spirometry, but there are few studies on documented spirometry use in everyday clinical practice. Methods: In a cross-sectional survey and study of the medical records of primary and secondary care COPD patients aged 18-75 in a Swedish region, patients with COPD were randomly selected from the registers of 56 primary care centres and 14 hospital outpatient clinics. Spirometry data at diagnosis ±6 months were analyzed. Results: From 1,114 patients with COPD, 533 with a new diagnosis of COPD during the four-year study period were identified. In 59% (n=316), spirometry data in connection with diagnosis were found in the medical records. Spirometry data with post-bronchodilator forced expiratory volume in one second (FEV1)/ vital capacity (VC) ratios were available in 45% (n=241). FEV1/VC ratio <0.70 were found in 160 patients, which corresponds to 30% of the patients with a new diagnosis. Lower age, female gender, current smoking, higher body mass index (BMI) and shorter forced exhalation time were related to COPD diagnosis despite an FEV1/VC ratio of ≥0.70. The most common problem in the quality assessment was an insufficient exhalation time. Conclusions: Only a third of Swedish patients with COPD had their diagnosis confirmed with spirometry. Our data indicate that female gender, current smoking, higher BMI and short exhalation time increase the risk of being diagnosed with COPD without fulfilling the spirometric criteria for the disease.

    New guidelines for hemorheological laboratory techniques2009In: Clinical hemorheology and microcirculation, ISSN 1386-0291, E-ISSN 1875-8622, Vol. 42, no 2, p. 75-97Article in journal (Refereed)
    Abstract [en]

    This document, supported by both the International Society for Clinical Hemorheology and the European Society for Clinical Hemorheology and Microcirculation, proposes new guidelines for hemorheological methods used in experimental and clinical studies. It is based on a similar document entitled: "Guidelines for measurement of blood viscosity and erythrocyte deformability" published in 1986 by the Expert Panel on Blood Rheology of the International Committee for Standardization in Hematology. Recent methods techniques and instruments, as well as new approaches to interpretation of results, are added to these new guidelines; wide spread adoption should improve comparability between hemorheological laboratories and increase the reliability of rheological tests.

    Ventilation/perfusion distributions revisited2016In: Current Opinion in Anaesthesiology, ISSN 0952-7907, E-ISSN 1473-6500, Vol. 29, no 1, p. 2-7Article, review/survey (Refereed)
    Abstract [en]

    Purpose of reviewA major cause of hypoxemia in anesthesia is ventilation-perfusion (V-A/Q) mismatch. With more advanced surgery and an aging population, monitoring of V-A/Q is of increasing importance.Recent findingsThe classic multiple inert gas elimination technique has been simplified with a new approach based on mass spectrometry. V-A/Q distributions can also be measured, at the bedside, by varying inspired oxygen concentration. MRI, 3-dimensional single photon emission computed tomography, positron emission tomography, and electrical impedance tomography enable imaging of perfusion and ventilation, and in some of the techniques also the distribution of inflammation. One-lung ventilation with thoracoscopy and capnothorax require careful monitoring of V-A/Q, made possible bedside by electrical impedance tomography. Carbon dioxide, but not air, for pneumoperitoneum enhances shift of perfusion to ventilated regions. Ventilatory support during cardiopulmonary resuscitation causes less V-A/Q mismatch when inspired oxygen concentrations are lower. Mechanisms of redistribution of lung blood flow by inhaled nitric oxide include endothelin-mediated vasoconstriction in collapsed lung regions.SummaryMethods are continuously developing to simplify measurement of V-A/Q and also to relate V-A/Q to inflammation. The recording of V-A/Q has helped to explain important aspects of gas exchange in thoracic anesthesiology and in intensive care medicine.

    Large Buffering Effect of the Duodenal Bulb in Duodenal Switch: a Wireless pH-Metric Study2017In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 27, no 7, p. 1867-1871Article in journal (Refereed)
    Abstract [en]

    Bariatric procedures result in massive weight loss, however, not without side effects. Gastric acid is known to cause marginal ulcers, situated in the small bowel just distal to the upper anastomosis. We have used the wireless BRAVO (TM) system to study the buffering effect of the duodenal bulb in duodenal switch (DS), a procedure in which the gastric sleeve produces a substantial amount of acid. We placed a pre- and a postpyloric pH capsule in 15 DS-patients (seven men, 44 years, BMI 33) under endoscopic guidance and verified the correct location by fluoroscopy. Patients were asked to eat and drink at their leisure, and to register their meals for the next 24 h. All capsules but one could be successfully placed, without complications. Total registration time was 17.2 (1.3-24) hours prepyloric and 23.1 (1.2-24) hours postpyloric, with a corresponding pH of 2.66 (1.74-5.81) and 5.79 (4.75-7.58), p < 0.01. The difference in pH between the two locations was reduced from 3.55 before meals to 1.82 during meals, p < 0.01. Percentage of time with pH < 4 was 70.0 (19.9-92.0) and 13.0 (0.0-34.6) pre and postpylorically, demonstrating a large buffering effect. By this wireless pH-metric technique, we could demonstrate that the duodenal bulb had a large buffering effect, thus counteracting the large amount of gastric acid passing into the small bowel after duodenal switch. This physiologic effect could explain the low incidence of stomal ulcers.

    Chronic rhinosinusitis impairs sleep quality: Results of the GA(2)LEN study2017In: Sleep, ISSN 0161-8105, E-ISSN 1550-9109, Vol. 40, no 1, article id zsw021Article in journal (Refereed)
    Abstract [en]

    STUDY OBJECTIVES: To analyse the prevalence of sleep problems in subjects with CRS and to determine whether the disease severity of CRS affects sleep quality.

    METHODS: Questionnaires were sent to a random sample of 45 000 adults in four Swedish cities. Questions on CRS, asthma, allergic rhinitis, co-morbidities, tobacco use, educational level and physical activity were included. CRS was defined according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) epidemiological criteria. The disease severity of CRS was defined by the number of reported CRS symptoms. Sleep quality was assessed using the Basic Nordic Sleep Questionnaire.

    RESULTS: Of the 26 647 subjects, 2249 (8.4%) had CRS. Reported sleep problems were 50-90% more common among subjects with CRS compared with those without or the total population. The prevalence of reported sleep problems increased in conjunction with the severity of CRS. After adjusting for gender, BMI, age, tobacco use, asthma, somatic diseases, physical activity level and educational level, participants with four symptoms of CRS (compared with subjects without CRS symptoms) displayed a higher risk of snoring (adj. OR (95% CI): 3.13 (2.22-4.41)), difficulties inducing sleep (3.98 (2.94-5.40)), difficulties maintaining sleep (3.44 (2.55-4.64)), early morning awakening (4.71 (3.47-6.38)) and excessive daytime sleepiness (4.56 (3.36-6.18)). The addition of persistent allergic rhinitis to CRS further increased the risk of sleep problems.

    CONCLUSIONS: Sleep problems are highly prevalent among subjects with CRS. The disease severity of CRS negatively affects sleep quality.

    Human Myocardial Protein Pattern Reveals Cardiac Diseases2012In: International Journal of Proteomics, ISSN 2090-2174, Vol. 2012, p. 342659-Article in journal (Refereed)
    Abstract [en]

    Proteomic profiles of myocardial tissue in two different etiologies of heart failure were investigated using high performance liquid chromatography (HPLC)/Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Right atrial appendages from 10 patients with hemodynamically significant isolated aortic valve disease and from 10 patients with isolated symptomatic coronary heart disease were collected during elective cardiac surgery. As presented in an earlier study by our group (Baykut et al., 2006), both disease forms showed clearly different pattern distribution characteristics. Interesting enough, the classification patterns could be used for correctly sorting unknown test samples in their correct categories. However, in order to fully exploit and also validate these findings there is a definite need for unambiguous identification of the differences between different etiologies at molecular level. In this study, samples representative for the aortic valve disease and coronary heart disease were prepared, tryptically digested, and analyzed using an FT-ICR MS that allowed collision-induced dissociation (CID) of selected classifier masses. By using the fragment spectra, proteins were identified by database searches. For comparison and further validation, classifier masses were also fragmented and analyzed using HPLC-/Matrix-assisted laser desorption ionization (MALDI) time-offlight/time-of-flight (TOF/TOF) mass spectrometry. Desmin and lumican precursor were examples of proteins found in aortic samples at higher abundances than in coronary samples. Similarly, adenylate kinase isoenzyme was found in coronary samples at a higher abundance. The described methodology could also be feasible in search for specific biomarkers in plasma or serum for diagnostic purposes.
